Question

Microsporogenesis: As the anther develops, the cells of the sporogenous tissue undergo meiotic division to form microspore tetrad. What would be the ploidy of the cell of the tetrad?

Answer 1

Hint: Anthers are bi-lobed structures that usually rest atop long slender stalks called filaments, often referred to as the pollen sac. Anthers are composed of tissues called microsporocytes that contain spore-producing cells.

Complete answer:
Within the microsporangia of seed plants, the microsporangium diploid cell undergoes meiosis and gives rise to four haploid microspores. Four nuclei are tetrahedrally arranged and are soon invested in cell walls. Every single cell of a microspore tetrad is haploid!! Tetrad literally means that there are four cells, all of which are haploid in nature and are produced in microspore mother cells by reduction division or meiosis.
The term tetrad means "four," which indicates there are four cells in it. They are produced by meiosis in the mother cell of the microspore. The number of cells after meiosis 1 is two, and the number of cells after meiosis 2 is four. Haploid (n) remains to be the ploid.

Additional Information: The nucleus of each mother cell of the microspore undergoes meiosis or reduction division and gives rise to four nuclei of haploids. Microsporogenesis is called this process. The four nuclei are tetrahedrally organized and are easily surrounded by cell walls. These are called microspores or grains of pollen now. Further, these microspores split once by mitosis to form two-celled microspores. Differentiates in the grain of pollen. The pollen grains soon dry up and become powdery as the tapetum is absorbed by each microspore. The partition walls are broken between the sporangia and the microspores are released through the anther's dehiscence.

Note: Ploidy, the number of chromosomes occurring in the nucleus of a cell, in genetics. The chromosomes occur in pairs in normal somatic (body) cells. ... The cell produces gametes, or germ cells, each containing half the usual or somatic chromosome number, during meiosis. Haploidy is called this disease.
