Question

In a dithecous anther, each pollen sac contains $1000$MMC. Which is the total number of pollen grains produced by anther?

• A. $4000$
• B. $8000$
• C. $16000$
• D. $32000$

Answer 1

The correct option is C $16000$

Total pollen sacs or microsporangia in bilobed dithecous anther =4

Each pollen sac has 100 microspore mother cells.

So total microspore mother cell in 4 pollen sacs=4X100=400

Meiosis produces 4 pollen grains or male gametophytes.

Meiosis in 400 microspore mother cell will produce=400X4=1600 pollen grains or male gametophytes.

So, the correct answer is '16000'.
