Question

How many microsporangia in each flower of solonacea family

Answer 1

Answer:

Explanation:

Each microspore mother cell gives birth to a pollen tetrad. So, 10 flowers (with 10 stamens in each) having 30 microsporangia in each and every microsporangium will make 48,000 pollen grains.

Answer 2

Explanation:

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.
