Question

The classification of the flowers as unisexual and bisexual is on the basis of:

• A. Presence of flowers at the tip of plant
• B. Presence of anther and filament of plant
• C. Presence of stamen and pistil in the flower
• D. Both A and C

Answer 1

Answer: (C)

Presence of stamen and pistil in the flower

A flower typically consists of petals, sepals, stamen and pistil (carpel). Stamen is the male reproductive part of a flower and pistil is the female reproductive part of a flower. Some flowers may carry both stamen and pistil in the same flower and are called bisexual flowers (as both the sexes are present in the same flower) and some flowers may have separate male and female flowers and are called unisexual flowers. The male flower has only the stamen and no pistil while, the female flower has only the pistil and no stamen.

So, the correct answer is option C,.
