What kind of fruit is avocado?
A fruit is the matured ovary of a flower. Basically, it consists of the ovary wall, or pericarp, which encloses one or more seeds (see figure right). The pericarp is differentiated into three layers of tissues: the outer layer is exocarp, which commonly is called the skin or rind. The middle layer is mesocarp which, generally,makes up the bulk of the pericarp. The inner layer is endocarp which, in some fruits is tough, leathery or hard, in other fruits is soft or fleshy.
