Parts of Fruits and Seeds
In botany, fruits are the mature ovaries of flowering plants along with any associated accessory parts, while seeds consist of the embryo enclosed by the seed coat. The pericarp, derived from the mature ovary, can be divided into endocarp, mesocarp, and exocarp layers. Fruits can be categorized into simple fruits (like berries and drupes), aggregate fruits (such as achenecetum and drupecetum), and multiple fruits (such as sorosis and syconium). Understanding the structure of fruits and seeds is essential in plant biology and horticulture.
