NEET · Biology · STD 12 - 1. sexual reproduction in flowering plants
Arrange the following in the correct development sequence related to microsporogenesis
A. Microspore tetrads
B. Sporogenous tissue
C. Pollen grains
D. Pollen mother cells
Choose the correct answer from the options given below :
- A D, A, C, B
- B B, D, A, C
- C B, D, C, A
- D A, D, C, B
Answer & Solution
Correct Answer
(B) B, D, A, C
Step-by-step Solution
Detailed explanation
(B) B, D, A, C
During the development of an anther, the cells of the sporogenous tissue undergo meiotic divisions to form microspore tetrads. Each cell of the sporogenous tissue acts as a pollen mother cell (PMC). The PMCs undergo meiosis to form microspore tetrads. As the anthers mature and dehydrate, the microspores dissociate from each other and develop into pollen grains.
The correct developmental sequence is:
Sporogenous tissue → Pollen mother cells → Microspore tetrads → Pollen grains.
This corresponds to the sequence B, D, A, C.
