Question

Assertion : In majority of angiosperms, there is monosporic type of embryo sac development.
Reason : The embryo sac develops from the single functional megaspore.
A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer 1

Correct Answer - A
`**` In a majority of flowering plants, one of the megaspores is functional while the other three degenerate.
`**` Functional megaspore develops into the female gametophyte (embyo sac). This method of embryo sac formation from a single megaspore is termed monosporic development.
