Question

Assertion : Proembryo stage is restricted to 2-celled stage
Reason : It has one basal and one apical cell.
A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If the assertion is false but reason is true

Answer 1

Correct Answer - D
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 cell towards the interior of the embryo sac and a large basal cell.
