Seed Structure and Function
- The primary purpose of a seed is to allow a plant to reproduce and disperse its offspring.
- Ovules are arranged in the ovaries of a plant, which are the female reproductive structures.
- The micropyle is a small opening in an ovule that allows pollen to enter and fertilize the egg cell.
- The kernel of a seed is defined as the embryo and its surrounding tissues, which are protected by the seed coat.
- Seeds are classified according to their kernel into three main categories: albuminous (presence of endosperm), exalbuminous (absence of endosperm), and naked (seed coat directly surrounds the embryo).
