Got it There are 4 microsporangium in a stamen . and each crotalia flower has 10 stamen.1 mmc = 4 pollen grains #10 stamen * 10 flower = 100 stamens #therefore 100 stamen * 4 = 400 microsporangium.therefore pollen grains produced = 400 * 30 mmc * 4 = 48000

In one individual plant of crotalaria, there are 10 flowers. Each flower contains microsporangia, which are structures responsible for producing pollen grains.

In each microsporangium of every seaman of all the flowers, there are 30 microspore mother cells. These mother cells undergo meiosis to produce haploid microspores, which eventually develop into pollen grains.

To determine the total number of pollen grains formed from that plant, we need to calculate the number of microspores produced in each microsporangium and then multiply it by the number of microsporangia present in all the flowers.

Here's the step-by-step calculation:

1. Calculate the number of microspores produced in each microsporangium:
- In each microsporangium, there are 30 microspore mother cells.
- Each mother cell undergoes meiosis and produces 4 microspores.
- So, in each microsporangium, there are 30 x 4 = 120 microspores.

2. Determine the number of microsporangia in all the flowers:
- Since there are 10 flowers in the plant, we need to multiply the number of microsporangia per flower by the total number of flowers.
- Let's assume there are 5 microsporangia per flower (this may vary depending on the species).
- Therefore, the total number of microsporangia in all the flowers is 10 x 5 = 50 microsporangia.

3. Calculate the total number of pollen grains formed:
- To get the total number of pollen grains, we need to multiply the number of microspores per microsporangium by the total number of microsporangia.
- Each microsporangium produces 120 microspores, and there are 50 microsporangia in all the flowers.
- Hence, the total number of pollen grains formed from that plant is 120 x 50 = 6000 pollen grains.

Therefore, from one individual plant of crotalaria, a total of 6000 pollen grains are formed.
