Question

Which one of the following is a non-endospermic seed?

• A. Sunflower
• B. Coconut
• C. Ground nut
• D. Wheat

Answer 1

The correct option is C Ground nut

Endosperm is a food-laden tissue, surrounding the embryo on all sides or either present on one side of the embryo. Depending on its presence or absence, seeds are of two types:

(i) Non-endospermic or exalbuminous seeds:

In these seeds like gram, pea, groundnut, the endosperm is completely consumed by the embryo.

(ii) Endospermic or albuminous seeds:

In monocots and castor bean (dicots) embryo does not consume all endosperm. So it persists in the mature seed. Such seeds are called as endospermic or albuminous seeds. In these seeds, food is stored in endosperm. In monocot seeds, the membranous covering present around radicle is called as coleorrhiza and around plumule is called as coleoptile.
