Assertion: Androecium is the third whorl of the flower. It is made up of stamens which produce pollen grains at the time of reproduction.
Reason: Pollination and fertilization are essential steps of reproduction in plants during which male gametes fuse with the ovule and a seed is produced inside the ovary.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true but R is not the correct explanation of A.
Reason — A is true as the androecium is the third whorl of a flower and consists of stamens that produce pollen grains.
R is true as pollination and fertilization are essential processes in plant reproduction, leading to seed formation inside the ovary.
The reason does not correctly explain why the androecium is the third whorl or that it is made of stamens. It only describes the process of reproduction. Therefore, Both A and R are true but R is not the correct explanation of A is the correct option.
