Question

Which among the following is incorrect about seeds based on the presence of the endosperm?

(a) Endosperm is usually absorbed and digested by the developing embryo

(b) Seeds that lack endosperm at maturity are called non-endospermic seeds

(c) Seeds that contain endosperm are called endospermic seeds

(d) In endospermic seeds, embryo gets absorbed and digested even before the seed gets detached from the plant

The question was posed to me at a job interview.

This interesting question is from Flowering Plants Morphology topic in chapter Morphology of Flowering Plants of Biology – Class 11

Answer 1

The correct answer is (d) In endospermic seeds, embryo gets absorbed and digested even before the seed gets detached from the plant

Easiest explanation: Endosperm is usually absorbed and digested by the developing embryo. Seeds that lack endosperm at maturity are called non-endospermic seeds. Seeds that contain endosperm are called endospermic seeds. In non-endospermic seeds, embryo gets absorbed and digested even before the seed gets detached from the plant.
