Question

How many statements are correct regarding stamen?
A stamen is a unit of androecium.
Stamen is known as microsporophyll.
Stamen is differentiated into filament and anther.
Stamen is the male sex organ of the flower.
A. One
B. Two
C. Three
D. Four

Answer 1

Hint: In flowering plants male reproductive organ is known as the stamen. Collectively these the stamens of a flower are known as Androecium. The number of this androecium carries greatly among different species of the flowering plants.

Complete answer:
Let’s explain each statement one by one-
Option -A- A stamen is a unit of the androecium
As stated earlier stamens of a flower are collectively known as Androecium. Therefore form this we can say that a stamen is a unit of androecium. So this statement about stamen is correct.
Option -B- Stamen is known as microsporophyll
Each anther is bilobed and each lobe has two chambers the pollen sacs. The anther contains microsporangia within these specialised compartments. Stamen also known as microsporophyll contains these compartments. So this option is also correct.
Option -C- Stamen are differentiated into filament and anther
A stamen is differentiated into filament which is a stalk-like structure which provides water and many important nutrients to anther and second part anther which contains microsporangia. So this option is also the correct description of the stamen.
Option -D- Stamen is the male sex organ of the flower
Stamen is the male reproductive organ of flowering plants containing pollen grains. It transfers pollen from anther to the pistil of the plant. So this statement is also correct.
So, all these statements are correct about stamen.

So, the correct answer to this question is an option” D” i.e. four.

Note: The anthers release pollen grains which is the most important process for flowering. This is carried by insects and via pollination great variations are seen. Pollination is necessary for plants to reproduce. Pollination is beneficial to both plants and insects.
