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.

  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Both Assertion and Reason are incorrect
Correct Answer: Option(c)
Solution: 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.
So, the correct answer is 'Assertion is correct but Reason is incorrect'.
