FAQ
Frequently Asked Questions
No. The endosperm is a separate nutritive tissue formed during fertilization. Cotyledons are the seed leaves of the embryo itself, which may absorb the endosperm or serve a similar nutritive function.
No. In many dicotyledonous plants (like beans and peanuts), the endosperm is absorbed by the developing embryo during seed maturation, and the mature seed is 'non-endospermic'. It is prominent in most monocots (like cereals) and some dicots.
Coconut water is the liquid endosperm of a young coconut. The solid white 'meat' is the cellular endosperm that develops later.
It is the source of most of the world's staple food calories. The endosperm of cereals like wheat, rice, and maize provides the carbohydrates and proteins in our diets. Its composition directly affects flour quality, nutritional value, and crop yield.
