Seeds and Nuts

Seeds and Nuts are two forms of plant structures often confused with each other. Seeds form from flowering plant ovules undergoing fertilization by bacteria; their contents include both an embryonic sac (called an endosperm ) as well as endosperm. Nuts on the other hand, are fruits with hard shells enclosing seeds inside.

Understanding the differences between seeds and nuts is critical for many reasons, from agriculture and dietary considerations to culinary use and culinary preparation. By understanding their individual properties we can make informed choices regarding consumption or usage.

Definition of seeds

Figure 01: Seeds

Seeds are the reproductive structures of plants that develop from fertilized ovules. They serve as a means of propagating new plants. A seed typically consists of a protective outer covering called the seed coat, which helps safeguard the internal components.

Inside each seed lies both an embryo, or young plant that remains underdeveloped at this stage, and an endosperm, which provides sustenance during germination. Seed sizes, shapes and dispersal mechanisms vary greatly according to plant species; each contributes towards the survival and reproduction of that particular species.

Seed anatomy and structure

Seed anatomy and structure refer to the internal and external components of a seed that contribute to its form and function.

Here is an overview of the key elements:

  1. Seed Coat: The seed coat, also known as the testa, is the outer protective layer of the seed. It provides physical protection against mechanical damage, pathogens, and desiccation (drying out). The seed coat may have various textures, colors, and patterns, depending on the plant species.

  2. Embryo: The embryo is the miniature, undeveloped plant contained within the seed. It consists of essential structures necessary for growth and development, including the radicle (embryonic root), plumule (embryonic shoot), and one or two cotyledons (seed leaves). The cotyledons may store nutrients to support the initial stages of germination.

  3. Endosperm: The endosperm is a nutrient-rich tissue surrounding the embryo. It serves as a source of energy and nutrients for the developing embryo during germination. In some seeds, the endosperm may persist until maturity, while in others, it is absorbed or used up during embryonic growth.

  4. Hilum: The hilum is a scar or mark on the seed coat where the seed was attached to the plant’s ovary wall. It represents the point of vascular connection through which nutrients were transported to the developing seed.

  5. Micropyle: The micropyle is a small opening or pore in the seed coat near the hilum. It allows for water absorption during germination and provides an entry point for the emerging radicle.

  6. Cotyledons: Cotyledons, as mentioned earlier, are the seed leaves of the embryo. They can store nutrients and may play a role in photosynthesis or absorbing nutrients from the endosperm. Depending on the plant species, seeds may have one or two cotyledons.

Understanding the anatomy and structure of seeds is important for seed identification, germination studies, and cultivation practices. The diverse features and adaptations of seeds contribute to their successful dispersal, survival, and establishment as new plants.

Types of seeds

Seeds come in various types, each with its own unique characteristics.

Here are some common types of seeds:

  1. True Seeds: True seeds are the typical seeds produced by flowering plants (angiosperms). They contain an embryo, endosperm, and seed coat. True seeds exhibit a wide range of sizes, shapes, and dispersal mechanisms.

  2. Pseudoseeds: Pseudoseeds, also known as achenes or cypselae, are specialized types of seeds found in plants such as sunflowers and dandelions. They have a single seed enclosed in a hardened, one-seeded fruit called a pericarp. Pseudoseeds are often dispersed by wind.

  3. Gymnosperm Seeds: Gymnosperms are a group of plants that produce seeds without the protection of an enclosed ovary. Instead, their seeds are usually borne on the surface of cone-like structures. Examples of gymnosperms include conifers, cycads, and ginkgo trees.

  4. Orchid Seeds: Orchids have unique seeds that are tiny, dust-like particles. They lack endosperm and have no food reserves. Orchid seeds rely on symbiotic relationships with specific fungi for germination and growth.

  5. Epiphytic Seeds: Epiphytic plants, such as some orchids and bromeliads, produce seeds adapted to grow on other plants. These seeds are usually small and have specialized structures or adaptations that allow them to attach to tree branches or bark and absorb nutrients from the air and rainwater.

  6. Recalcitrant Seeds: Recalcitrant seeds, also known as desiccation-sensitive seeds, have a short lifespan and cannot withstand drying. They are unable to tolerate low water content and cannot be stored for long periods. Examples of recalcitrant seeds include cocoa beans and certain tropical tree seeds.

  7. Orthodox Seeds: Orthodox seeds, in contrast to recalcitrant seeds, are capable of surviving desiccation (drying out). They can be stored for extended periods under specific conditions, making them suitable for seed banks and long-term storage.

Understanding the different types of seeds is important for plant propagation, agriculture, and conservation efforts. Each type has its own germination requirements, dispersal mechanisms, and storage considerations. By recognizing these variations, researchers and growers can make informed decisions about seed collection, storage, and cultivation practices.

Seed dispersal mechanisms

Seed dispersal mechanisms are the various ways by which seeds are dispersed or spread away from the parent plant. These mechanisms play a crucial role in plant reproduction and the colonization of new habitats. Here are some common seed dispersal mechanisms:

Wind Dispersal

Some seeds have adaptations that allow them to be carried by the wind over long distances. They often have lightweight structures, such as feathery or wing-like structures, or they may have structures that create air resistance, like a parachute. Examples of wind-dispersed seeds include those of dandelions and maple trees.

Animal Dispersal

Animals, both vertebrates and invertebrates, can aid in seed dispersal through various means. Some seeds have structures that attach or adhere to the fur, feathers, or bodies of animals, allowing them to be transported to new locations. Animals may also consume fruits containing seeds and then excrete them elsewhere, aiding in seed dispersal. Examples of animal-dispersed seeds include those dispersed by birds, mammals, and ants.

Water Dispersal

Seeds that can float or survive in water can be dispersed by bodies of water, such as rivers, streams, or oceans. These seeds may have buoyant structures or protective coatings that enable them to remain viable during water dispersal. Coconuts and water lilies are examples of plants that rely on water dispersal.

Gravity Dispersal

Some seeds rely on gravity to disperse them away from the parent plant. These seeds often have structures that allow them to fall to the ground and roll or bounce away from the parent plant. Gravity dispersal is common in plants with heavy or dense seeds, such as acorns from oak trees.

Explosive Dispersal

Certain plants have seed pods or capsules that burst open when mature, propelling the seeds away from the parent plant. This explosive release can be triggered by factors like heat, raindrops, or physical disturbances. Examples of plants with explosive dispersal mechanisms include touch-me-not plants and some legumes.

Human Dispersal

Humans can also play a role in seed dispersal, intentionally or unintentionally. Human activities, such as agriculture, gardening, and transportation, can introduce seeds to new environments, often far beyond their natural range.

Seed dispersal mechanisms contribute to the survival and diversity of plant species by allowing seeds to colonize new areas, escape competition with parent plants, and establish populations in different habitats. Understanding these mechanisms is valuable for studying plant ecology, conservation, and the restoration of ecosystems.

Definition of Nuts

Figure 02: Nuts

Nuts are a type of fruit characterized by an outer hard shell encasing one seed or kernel and are considered dry fruits. Common sources for nuts are flowering plant ovary walls. Nuts come in all sorts of shapes, sizes, and flavors and are frequently eaten as snacks or used as an ingredient in cooking or culinary applications.

Botanically speaking, nuts can be described as indehiscent fruits whose shells do not naturally split open to release their seed. Instead, these hard shells serve as protection for its seeds inside. Nuts can be found across various plant families such as Rosaceae (including almonds and peanuts) and Juglandaceae (such as walnuts).

Culinary definitions of nuts can differ, often including some fruits that do not meet the botanical definition. Peanuts are legumes but are frequently considered nuts due to their similar culinary use and characteristics.

Nuts are known for their nutritional content and rich source of healthy fats, proteins, fiber, vitamins, and minerals that offer multiple health benefits, including cardiovascular wellness management and weight reduction. Nuts also make an excellent energy-packed source that provides an energy boost for day-to-day activity as well as offering important micronutrient intake to maintain overall good health and improve weight control.

Nuts are dry fruits characterized by hard shells which enclose one seed or kernel and are widely enjoyed for their delicious flavors, textures, and nutritional qualities; as part of culinary traditions worldwide, they play a pivotal role.

Nut anatomy and structure

Nut anatomy and structure refer to the internal and external features of nuts that contribute to their form and function.

Here is an overview of the key elements:

  1. Hard Shell: Nuts are characterized by a hard, rigid outer covering called the shell or pericarp. The shell provides protection to the seed within and can vary in thickness and texture depending on the nut variety. It helps safeguard the seed from physical damage, pests, and environmental factors.

  2. Seed: The seed, also known as the kernel, is the edible part of the nut. It is located within the shell and contains the embryo of the plant. The seed is often rich in nutrients and serves as a source of energy for the developing plant.

  3. Cotyledons: Cotyledons are the seed leaves of the embryo. In nuts, the cotyledons are usually fleshy or solid, providing nourishment to the developing plant during germination. The number and structure of cotyledons can vary depending on the nut species.

  4. Hilum: The hilum is a scar or marks on the nutshell where it was attached to the plant’s ovary wall. It represents the point of vascular connection through which nutrients were transported to the developing seed.

  5. Raphe: The raphe is a small ridge or line on the surface of some nuts, running from the hilum to the opposite end of the seed. It represents the point of attachment of the seed to the ovary wall.

  6. Endosperm: In some nuts, such as almonds and cashews, there may be a thin layer of endosperm surrounding the embryo. The endosperm provides additional nourishment and is often consumed along with the seed.

Understanding the anatomy and structure of nuts is important for various purposes, such as nut identification, culinary use, and processing. The hard shell protects the seed and allows for long-term storage. The edible seed within the shell provides nutrition and contributes to the flavor and texture of the nut. By recognizing these features, individuals can make informed choices about nut consumption, cooking, and utilization in various applications.

Nut cultivation and harvesting

Nut cultivation and harvesting involve specific practices to ensure the successful growth, development, and harvesting of nut-bearing trees.

Here are the general steps involved in nut cultivation and harvesting:

Site Selection

Choose a suitable location for nut cultivation. Consider factors such as soil type, drainage, sunlight exposure, and climatic conditions. Different nut tree species have specific environmental requirements, so ensure the selected site meets the needs of the particular nut tree you intend to cultivate.


Prepare the planting area by clearing weeds and debris. Dig holes that are wide and deep enough to accommodate the nut tree’s root system. Place the tree in the hole, ensuring the root collar is level with or slightly above the soil surface. Backfill the hole with soil and firmly pack it around the roots. Provide appropriate support, such as stakes, if needed.


Nut trees require adequate water to establish and grow. Provide regular irrigation, especially during dry periods, to ensure proper hydration. The water requirements may vary depending on the tree species, soil type, and climate. Avoid overwatering or waterlogging, as it can lead to root rot and other issues.


Nut trees benefit from regular fertilization to ensure optimal growth and nut production. Conduct a soil test to determine the nutrient deficiencies and adjust the fertilizer application accordingly. Use a balanced fertilizer or one specifically formulated for nut trees. Apply the fertilizer as directed, considering the tree’s age and size.


Prune nut trees to maintain their shape, promote air circulation and remove damaged or diseased branches. Pruning also helps manage tree size, optimize nut production, and improve overall tree health. Follow proper pruning techniques and timing specific to the nut tree species.

Pest and Disease Management

Nut trees can be susceptible to various pests and diseases. Monitor the trees regularly for signs of infestation or disease, such as leaf discoloration, wilting, or pest presence. Implement appropriate pest management strategies, including cultural practices, biological control, and judicious use of pesticides when necessary. Consider using integrated pest management (IPM) techniques for sustainable and environmentally friendly pest control.


Nut trees have specific signs indicating when the nuts are ready for harvest. This can include changes in color, husk splitting, or nuts dropping from the tree. Harvest the nuts by carefully collecting them from the ground or by shaking the tree branches. Some nuts, like almonds, may require mechanical shaking to facilitate harvesting. Remove the husks, if applicable, and allow the nuts to dry in a well-ventilated area before storage or further processing.


Proper storage is essential to maintain the quality and prevent spoilage of harvested nuts. Store the nuts in cool, dry conditions to minimize moisture and pest damage. Use appropriate containers, such as mesh bags or airtight containers, to allow airflow while preventing moisture absorption. Periodically check the stored nuts for any signs of deterioration or pest activity.

Nut cultivation and harvesting require patience, proper care, and attention to detail. Following recommended practices and staying informed about the specific requirements of the nut tree species you are cultivating will contribute to successful nut production.

Differences Between Seeds and Nuts

Seeds and nuts are both plant reproductive structures, but they differ in various aspects.

Here are some key differences between seeds and nuts:

  1. Structure: Seeds are the reproductive structures produced by flowering plants (angiosperms) and gymnosperms. They consist of an embryo, an endosperm (in some cases), and a protective seed coat. Nuts, on the other hand, are a type of seed with a hard shell that encloses a single seed or kernel.

  2. Edibility: While all nuts are seeds, not all seeds are nuts. Nuts are specifically defined as seeds with a hard, indehiscent (non-splitting) shell that does not naturally open to release the seed. Some seeds, like beans and peas, are not considered nuts because they have a different structure and are typically consumed in different ways.

  3. Culinary Use: Nuts are commonly consumed as a food item, either raw or roasted, and are used in various culinary applications, including snacking, baking, cooking, and as ingredients in sauces, spreads, and confectionery. Seeds, on the other hand, have a broader range of culinary uses. They can be consumed as seeds themselves (e.g., sunflower seeds), used for sprouting, pressed for oils, or utilized as ingredients in different dishes.

  4. Botanical Classification: Seeds are a broad term that encompasses various structures produced by plants for reproduction, including nuts, grains, legumes, and more. Nuts, as mentioned earlier, are a specific type of seed with a hard shell. They are typically derived from the ovary wall of a flowering plant and are classified as dry fruits.

  5. Nutrient Composition: Nuts are known for their nutritional profile and are often rich in healthy fats, protein, fiber, vitamins, and minerals. They are considered calorie-dense and provide a range of health benefits. Seeds, on the other hand, can have varying nutrient compositions depending on the specific seed type. Some seeds are rich in healthy fats (e.g., chia seeds), while others are high in carbohydrates (e.g., grains like rice or wheat) or protein (e.g., legumes like lentils).

  6. Botanical Diversity: Nuts are more limited in terms of botanical diversity compared to seeds. Nuts commonly include varieties such as almonds, walnuts, cashews, and pecans. Seeds, encompass a much broader range of plant structures and include a wide array of plants, such as grains (rice, wheat), legumes (beans, peas), and various smaller seeds (chia, flax, sesame).

Understanding the distinctions between seeds and nuts helps clarify their specific characteristics, culinary applications, and nutritional attributes. While all nuts are seeds, the term “nut” refers to a specific subset of seeds with particular structural and culinary features.

Botanical Classification of Seeds and Nuts

Seeds and nuts are classified differently based on their botanical characteristics.

Here is a brief overview of their botanical classification:


Seeds are the reproductive structures produced by plants and are classified based on the type of plant that produces them:

  1. Angiosperm Seeds: Angiosperms are flowering plants that produce seeds within a protective structure called the ovary. Angiosperm seeds can be further categorized into:

  • Monocotyledonous Seeds: Monocots, such as grasses, lilies, and orchids, have seeds with a single cotyledon or seed leaf. Examples include corn, rice, and wheat.
  • Dicotyledonous Seeds: Dicots, such as beans, peas, and sunflowers, have seeds with two cotyledons or seed leaves. Examples include peas, lentils, and soybeans.

  2. Gymnosperm Seeds: Gymnosperms are non-flowering plants that produce seeds in open structures (cones) instead of enclosed ovaries. Gymnosperm seeds are not protected by a fruit and are often exposed or borne on the surface of scales. Examples include pine seeds, spruce seeds, and cycad seeds.


Nuts are a specific type of seed with certain botanical characteristics. They are classified as dry fruits, specifically indehiscent fruits, which means their shells do not naturally split open to release the seed. Nuts are typically derived from the ovary wall of a flowering plant. Common examples of nuts include almonds, walnuts, cashews, and pecans.

It’s important to note that the culinary definition of nuts may vary and can sometimes include seeds that do not meet the botanical classification of nuts. For instance, peanuts are actually legumes, but they are often referred to as nuts due to their similar culinary uses and characteristics.

Understanding the botanical classification of seeds and nuts provides insights into their evolutionary relationships, reproductive structures, and biological characteristics.
