Biology Question on Pre-Fertilisation: Structures And Events
Number of meiotic divisions necessary to produce 100 seeds in cyperus is
A
100
B
200
C
300
D
400
Answer
200
Explanation
Solution
In Cyperaceae, one microspore mother cell produces only one pollen grain (microspore) as the three microspores degenerate. Thus, for producing 100 seeds 100 division 100 microspone mother cell and 100 divisions in 100 megaspore mother cells will take in place. Thus, in all 200 meiotic divisions are required to produce 100 seeds.
