Question

In an angiosperm, how many microspore mother cells are required to produce 100 pollen grains ?

(a) 25 

(b) 50

(c) 75 

(d) 100

Answer 1

Correct option (a) 25

In angiosperms, each Microspore Mother Cell (MMC) undergoes meiosis to produce four microspores which develop into pollen grains. Thus, to produce 100 pollen grains, 25 microspore mother cells are required.
