Is endosperm absent in orchids?

Answer: (b) Orchid seed is a non-endospermic seed, i.e., endosperm is absent in it. Endosperm is a nourishing tissue present in the seed which nourishes the developingembryo. In orchid seed endosperm is absent because it is used up during the time ofseed development.
