Answer:
The total number of pollen grains produced in large staminal bundles of a Pisum consisting of 20 flowers is 32000.
Explanation:
A typical Pisum flower contains 10 anthers, which are dithecous. The term 'dithecous' means that the anther consists of two lobes.
Thus, according to the given information, each anther lobe of the Pisum flower consists of 80 pollen grains.
∴ The total number of pollen grains in each anther would be = 80 + 80 = 160.
Again, since each flower contains 10 such anthers, thus the total number of pollen grains in a flower would be = 160 × 10 = 1600 pollen grains.
Now, the plant contains 20 such flowers.
∴ The total number of pollen grains produced by the plant together is = 1600 × 20 = 32000.
