Question

"The spongy cotyledon increases in size as it absorbs food material stored in the endosperm ".Do you agree with this statement ? why or why not?

Answer 1

Endosperm, unlike the cotyledon, originates by the union of male nuclei and polar nuclei of embryo sac.

In dicots, endosperm is digested completely before the seed germinates, whereas cotyledon remains until the seedling is capable of photosynthesis.

In dicots, cotyledon completely absorbs the food stored in endosperm.
