Question

pollen grains are formed by which division in locules of anther

Answer 1

The Pollen grains are created by the process of the meiotic splitting in the pollen mother cell (PMC) or the microsporangium.

Each of these are made up of 4 microsporangia.

Each of the micropore is then developed by the mitosis to form a pollen grain.

The generative cell that is inside the pollen grain would later get divided to create two sperm cells.

Answer 2

Explanation:

The pollen grains are developed in the Pollen Mother Cell (PMC) or microsporangium through the method of meiotic splitting. Each one consists of 4 microsporangia. The mitosis then develops each of the microspores to form a grain of pollen.  

Pollen grain is created after meiosis and the mitosis process takes place alternately. The division of cells would be 2n and n forming procedures separated by a layer of ‘Callose cell wall’.
