Question

Assertion : Ex-albuminous seeds do not possess any residual endosperm, as it is completely consumed during embryo development.
Reason: Wheat, castor, pea and groundnut are all the examples of ex-albuminous seeds.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

In some seeds, the endosperm persists in the seed as food storage tissue. Such seeds are called endospermic or albuminous, e.g., Castor, Maize, Wheat, Barley, rubber, coconut. In others the endosperm is completely eaten up by growing embryo. The food for later development of embryo is then stored in cotyledons which become massive. Such seeds are non-endospermic or ex-albuminous, e.g., pea, gram, bean, groundnut.
