Question

A flower has 10 stamens each having bilobed dithecous anther. If each microsporangium has 5 pollen mother cells, how many pollen grains would be produced by the flower ?

• A. 1600
• B. 200
• C. 400
• D. 800

Answer 1

The Correct Option is D

The correct answer is (D) : 800.

Answer 2

The correct answer is: (D) 800.

Let's go through the calculations step by step to ensure accuracy:

• 1. Number of microsporangia per stamen: Since each anther has 2 lobes, and each lobe contains 2 microsporangia, each stamen has 2 × 2 = 4 microsporangia.
• 2. Total number of microsporangia in the flower: With 10 stamens, the total number of microsporangia is 10 × 4 = 40 microsporangia.
• 3. Total number of pollen mother cells: Since each microsporangium has 5 pollen mother cells, the total number of pollen mother cells is 40 × 5 = 200 pollen mother cells.
• 4. Total number of pollen grains: Each pollen mother cell produces 4 pollen grains, so the total number of pollen grains produced is 200 × 4 = 800 pollen grains.

Thus, the flower would produce 800 pollen grains.
