Biology Question on sexual reproduction in flowering plants
In grasses what happens in micro spore mother cell for the formation of mature pollen grains
A
One meiotic and two mitotic divisions
B
One meiotic & one mitotic divisions
C
One meiotic division
D
One mitotic division
Answer
One meiotic and two mitotic divisions
Explanation
Solution
In grasses, the formation of mature pollen grains from a microspore mother cell involves: (A) One meiotic and two mitotic divisions. During this process, meiosis occurs first to reduce the chromosome number, followed by two mitotic divisions to produce a multicellular structure called a mature pollen grain, which contains two cells - a vegetative cell and a generative cell. This generative cell is essential for fertilization in plants.
