Question

Assertion : Proembryo stage is restricted to 2-celled stage.
Reason : It has one basal and one apical cell

• A. Both assertion and reason are true and reason is a correct explanation of the assertion.
• B. Both assertion and reason are true but reason is not a correct explanation of the assertion.
• C. Assertion is true but Reason is false
• D. Both Assertion and Reason are false
• E. Assertion is false but Reason is true

Answer 1

The correct option is E Assertion is false but Reason is true

From the 2-celled stage until the initiation of organs the embryo is commonly called proembryo. In the majority of angiosperms the zygote divides transversely, resulting in small apical sell towards the interior of the embryo sac and a large basal cell.
