What is the function of Mesocarp?
Likewise, what is the function of Endocarp?
In dry fruits the endocarp plays a primary role in seed dispersal. Dry fruits are generally categorized as either dehiscent or indehiscent depending on whether or not the pericarp splits open at maturity. Wisteria represents an extreme case in which the pods are explosive, ejecting the seeds very long distances.
Additionally, what is the Exocarp made of?
The exocarp consists of a cuticle and a layer of epidermal cells up to 20 μm in places. In surface view the cuticle is striated. Epidermal cells are polygonal in shape and vary in size up to about 133 μm. Stomata are present but not numerous.
A coconut is all of these: a seed, a fruit and a nut! Coconut is a seed because it is the reproductive part of the tree, coconut is a fruit because it is a fibrous one-seeded drupe and coconut is a nut because a loose definition of a nut is nothing but a one-seeded 'fruit'.
