Question

Number of spindle apparatii formed to produce 4 male gametes from its pollen mother cell

• A. 8
• B. 5
• C. 11
• D. 7

Answer 1

The correct option is A 8

The male gametes of angiosperms consist of two sperm cells within a pollen grain or a pollen tube. They are derived from a single generative cell, which is formed as the smaller cell by unequal cell division in the microspore after meiosis. Each haploid (n) male gametophyte produces two haploids (n) sperm by mitosis. Each pollen grain contains one male gametophyte. The pollen mother cell requires one cycle of meiosis to produce 4 male gametes and twice the number of spindle apparatus.

So, the correct answer is '8'.
