called a mesocarp (F), and a hard inner layer called
an endocarp (E) that surrounds a large seed. The
endocarp (A) contains three germination pores at one
end, one of which the sprouting coconut palm grows
through. The "meat" of the seed is endosperm tissue
(B) and a small, cylindrical embryo is embedded in
this nutritive tissue just opposite the functional
germination pore. The seed is surrounded by an outer
brown layer called the seed coat or testa. This is the
brown material that adheres to the white "meat" or
endosperm when it is removed from the endocarp
shell. "Coconut water" (C) is multinucleate liquid
endosperm that has not developed into solid tissue
composed of cells. Copra comes from the meat of
dried coconuts, while coir fibers are derived from the
fibrousmesocarp.
