NEET BIOLOGY

Detailed explanation-1: -Microsporogenesis is the formation of microspores in the form of tetrads, which later separate and are called pollen grains. Microspore mother cell (2n) undergoes meiosis for the formation of haploid pollen grains formed first in the form of spore tetrads.

Detailed explanation-2: -Complete answer: During microsporogenesis, meiosis occurs in microspore mother cells.

Detailed explanation-3: –A microspore mother cell also known as microsporocyte is a diploid cell in plants. These microspore mother cells undergo meiosis division to give rise to four haploid microspores.-Each of these microspores divide and redivide mitotically to form pollen grains.

Detailed explanation-4: -Sporogenous Tissue These are located at the centre of each microsporangium in a young anther. With the development of the anther, the sporogenous cells undergo meiotic division to form microspore tetrads. Each sporogenous cell is known as a pollen mother cell or microspore mother cell.

Detailed explanation-5: -pollen development The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell.
