Question

Pollen grains are produced by
A) Ovary
B) Anther
C) Stigma
D) Petal

Answer 1

Hint: Pollen grains or the male gametes are formed within the anther sac through meiotic cell division.

Complete Answer:
Option A: Ovary is an organ found enclosed within the female reproductive system which is responsible for the production of the female reproductive organ i.e. ovum. Therefore, this is the incorrect option.

Option B: Anther is defined as that part of the stamen which produces pollen grains. herefore, this is the correct option.

Anther is the reproductive structure of a flower. It is present at the top of the filament of the male stamen and produces pollen grains. The pollen grains can be dispersed by wind. The other parts of the flower are,
Calyx- Outermost whorl of the flower
Corolla- Second whorl of the flower and has many petals
Androecium- Male reproductive part of the flower
Gynoecium- Female reproductive part of the flower

Option C: The receptive tip of the carpel of the flower is called a stigma which consists of several fused carpels. herefore, this is the incorrect option.

Option D: The petals are defined as the modified versions of the leaves that surround the female reproductive organ in the gynoecium. herefore, this is the incorrect option.

Thus, the correct alternative for this question is Option B) anther.

Note: The male reproductive part of the flower consists of Stamen- Third whorl and consists of two parts,
- Anther - responsible for pollen formation
- Filament - helps in keeping anther in place
