Stamen represents ___________.

Stamens are the units of the androecium. These are male reproductive organs. Stamens bear anthers which contain the sporogenous tissues. The sporogenous tissues form the microspores that mature to develop into pollen grains. So, pollen grains are the microsporangium that bear the male gametes and stamens are the microsporophylls that bear the microsporangia.

A. Stamens represent microsporophylls.

B. Pollen grains represent microsporangia.

C. Ovule represents megasporangium.

D. Carpel represents megasporophyll.

Hence, the correct answer is 'Microsporophyll'
