Question

Assertion : An angiospermous flower represents the modified condensed shoot which performs the function of sexual reproduction.
Reason: The fertile leaves of the shoot become modified into microsporophylls and megasporophylls which bear ovules and anthers respectively.

• 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)

A flower is a modified condensed shoot specialised to carry out the function of sexual reproduction in angiosperms. Like a branch, it arises in the axil of a small leaf like structure called bract. The receptacle (thalamus or torus) of a flower supports all the floral appendages {i.e., sepals, petals, stamens and carpels). The receptacle consists of several crowded nodes which are separated by condensed internodes. The fertile leaves of the shoot become microsporophylls (= stamens) and megasporophylls (= carpels) which bear anthers and ovules respectively. The anthers produce pollen grains and the ovules possess eggs.
