Question

 The stamen represents

A) Microsporangia

B) Male gametophyte

C) Male gamete

D) Microsporophylls

Answer 1

Hint: The male reproductive organ is the stamen. A pollen sac (anther) and a long filament of support make up the pollen sac. The anther is held in position by this filament, which allows pollen to be distributed by wind, insects, or birds. The brilliantly coloured sections of a flower are called petals.

Complete answer:

A stamen is a flowering plant species' male reproductive organ that contains pollen.  The stamen is made up of an anther attached to a filament. The microsporangia, which will eventually grow into pollen grain, live inside the anther. Anther is the site of pollen growth, and a stalk-like filament, which transmits water and nutrients to the anther and positions it to help in pollen dispersal.

The androecium is made up of stamens. They are the sexual organs of males. Stamens have anthers that contain sporogenous tissues. Microspores are formed by sporogenous tissues and mature to become pollen grains. Pollen grains are microsporangium that carry male gametes, and stamens are microsporophylls that bear microsporangia. So, Stamens represent microsporophylls. 

Pollination is the process through which flowering plants reproduce sexually. Male sex organs called stamens and female sex organs called pistils are found in the flowers. The pollen must be transferred to the stigma, which is a component of the pistil.

Thus the correct answer is option ‘D’.

Note: The stigma is a sticky knob located at the top of the pistil. The style, which is a long, tube-like structure, is joined to it. The style leads to the ovary, which includes female egg cells known as ovules.
