Question

The mature seeds of plants such as gram and peas, possess no endosperm, because

• A. Endosperm is not formed in them
• B. Endosperm gets used up by the developing embryo during seed development
• C. There is no double fertilization in them
• D. These plants are not angiosperms

Answer 1

The correct option is B Endosperm gets used up by the developing embryo during seed development

These plants are not angiosperms:

Gram and pea are flowering plants that have their seeds enclosed in a fruit. They are angiosperms.

There is no double fertilization in them:

Double fertilisation is common in all angiosperms.

Endosperm is not formed in them:

Double fertilisation leads to the formation of endosperms.

Endosperm gets used up by the developing embryo during seed development:

Endosperm is a nutritious tissue that nourishes the growing embryo in the seeds of angiosperms. In some seeds, the endosperm is not present in mature seeds and such seeds are called non-endospermous because it is completely absorbed at maturity.

Final answer:

d. Endosperm gets used up by the developing embryo during seed development
