Arrange the following terms in the correct developmental sequence: Pollen grain, sporogenous tissue, microspore tetrad, pollen mother cell, male gametes.
Explanation Sporogenous tissue. Each cell of the sporogenous tissue acts as a pollen mother cell. 2. Pollen mother cell. Each pollen mother cell undergoes meiosis. This is called microsporogenesis. 3. Microspore tetrad. By microsporogenesis, four haploid microspores are formed. This is called a microspore tetrad. 4. Pollen grain. After the development of the anther, the microspores dissociate to form pollen grains. 5. Male gamete. After maturation, the pollen grains develop into male gametes. Final answer Each microsporangium has sporogenous tissue, which undergoes differentiation to produce pollen mother cell (also known as microspore). The sporogenous cells are diploid, while the pollen grains produced are haploid in nature. The pollen grain is the first cell of the male gametophyte in which the male gamete develops.
