Question

If the number of stamen in a flower of mustard is 6 and the number of microspore mother cell in each pollen sac is 100 then total number of male gametes produced per flower are

• A. 19200
• B. 2400
• C. 3200
• D. 1600

Answer 1

The correct option is A 19200

A mustard flower has six dithecous stamens.

Number of microspore mother cells in one stamen $=100\times 4=400$

Total number of microspore mother cells in six stamens $=400\times 6=2400$

Now, each microspore mother cell undergoes meiosis and produces $8$ pollen grains.

Therefore, number of pollen grains produced by $2400$ microspore mother cells $=2400\times 8=19200$

Thus the correct answer is option A.
