Question

A certain number of flowers can be arranged in groups of 10, 20, and 25 with no flower left behind. Find the number of flowers.

Answer 1

Answer:

Crotalaria is a member of Papilionaceae, in which 10 stamens are present in flower. Each stamen has 4 microsporangia (i.e., 10x4= 40), in which microspore mother cells are found. Each microspore mother cell gives rise to a pollen tetrad (i.e., 40x4= 160). So, for 1 flower having 30 microsporangia it would be 160x30= 4800 pollen grains. Thus, if we have to calculate for 10 flowers then it would be 4800x10 = 48000 pollen grains.
