Question

Write a short note on mocrosporogenesis

Answer 1

Answer:

The formation of microspores inside the microsporangia (or pollen sacs) of seed plants. A diploid cell in the microsporangium, called a microsporocyte or a pollen mother cell, undergoes meiosis and gives rise to four haploid microspores.

Answer 2

Microsporogenesis process takes place inside the microsporangia inside the anther in which a diploid cell in the microsporangium, called a microsporocyte or a pollen mother cell, undergoes meiosis and gives rise to four haploid microspores inside the microsporangia (or pollen sacs) of seed plants.
These four nuclei are arranged tetrahedrallyand are soon invested with cell walls. They are the microspores or pollens which soon dry up and become powdery while the tapeworm become absorbed.

The nucleus of each microspore mother cell undergoes meiosis or reduction division and gives rise to four haploid nuclei. This process is called microsporogenesis. The four nuclei are arranged tetrahedrally and soon get enclosed with cell walls. These are now called microspores or pollen grains. These microspores fiurther divide once by mitosis to form two-celled microspore. differentiates into pollen grain. Each microspore The pollen grains soon dry up and become powdery while the tapetum gets absorbed. The partition walls between the sporangia get destroyed and the microspores are liberated by the dehiscence of the anther.
