Fruit Classification And Structure — a labelled NEET Biology diagram with a definitions lexicon.
Fruit Classification and Structure Labelled parts: Simple Fruits, Aggregate Fruits, Composite Fruits, Drupe, Berry, Pome, Dry Fruits, Legume, Capsule, Caryopsis, Etaerio (aggregate of berries), Sorosis (pineapple), Syconus (fig), pericarp, exocarp, mesocarp, endocarp, placenta, receptacle, core, drupeelts, locule, carpel, ovary, seed coat, seeds. A drupe is a fleshy fruit with a single, hard, stony endocarp (pit or stone) surrounding the seed. Examples include mango and coconut. FYI: The hard pit (stone) is the defining feature of a drupe, distinguishing it from berries or capsules. A berry is a fleshy fruit derived from an ovary, typically having a soft, pulpy pericarp that is eaten by animals. The entire ovary wall is fleshy. FYI: Tomatoes and grapes are classic examples of berries, even though they are botanically classified as fruits. A fleshy fruit derived from the receptacle, where the edible part is typically formed by the hypanthium (floral cup). Examples include apples and pears. FYI: Pome fruits are characterized by having a core containing seeds, which is often visible and distinct from the fleshy outer part. A fruit derived from a single ovary, characterized by having two valves (sutures) that split open at maturity. These fruits are typical of plants in the Fabaceae family (e.g., peas, beans). FYI: Leguminous plants possess root nodules containing nitrogen-fixing bacteria, primarily Rhizobium , which converts atmospheric N₂ into usable ammonia. A type of dry fruit where the seed coat (pericarp) is fused to the outer layer of the fruit wall (pericarp). Examples include grains like wheat and maize. FYI: In caryopsis, the edible part is the grain, and the fusion of the seed coat with the fruit wall makes it difficult to distinguish from the surrounding plant tissue. The middle layer of the fruit wall (pericarp). Its thickness and texture vary greatly depending on the fruit type (e.g., the fleshy part of a mango). FYI: In fruits like mango, the mesocarp is the primary component of the edible pulp, while the exocarp and endocarp form the skin and inner layer, respectively. The innermost layer of the fruit wall (pericarp) that surrounds the seed. It can be hard (stone fruit) or soft. FYI: In stone fruits (drupes) like peaches, the hard, stony layer surrounding the seed is the endocarp, while the outer skin is the exocarp. The outermost layer of the fruit wall (pericarp). It is often the skin or peel of the fruit. FYI: The exocarp provides protection and determines the visible color and texture of the fruit; for example, the skin of a banana is the exocarp. A type of inflorescence where the flowers are arranged in a spiral or whorled pattern around a central axis. This term is less common in standard NEET curricula but refers to a specific floral arrangement. FYI: If encountered in advanced botany, remember that inflorescence types describe the arrangement of flowers, which is crucial for pollination and seed dispersal. A dense, cone-like cluster of numerous, small, and often inconspicuous flowers or fruits. This arrangement is typical of plants like Tradescantia or certain grasses. FYI: Sorosis is a characteristic feature of certain plant families, indicating a mass production of small reproductive units, maximizing dispersal potential. A type of fleshy, hollow, spherical inflorescence that develops into a fruiting body, often containing numerous individual flowers or spores inside. This is characteristic of the genus Syconium (e.g., cup fungi). FYI: While often associated with fungi, the term describes a structure that functions similarly to a fruit/inflorescence, containing reproductive units within a protective outer wall.
