Question

Meiosis is best observed in dividing
A. Cell of lateral meristem
B. Cells of apical meristem
C. Microsporocytes
D. Microspores and anther wall

Answer 1

Hint: The cell division includes mitotic and meiotic division. In meiosis, the number of chromosomes becomes half. Cells of lateral and apical meristem do not undergo reductional division of chromosomes. Microspores develop in microsporocytes. Microspores have a haploid number of chromosomes.

Complete answer:
Cell division includes two processes mitosis and meiosis. Mitosis mainly occurs in somatic cells while the meiosis occurs in the reproductive cells (gametes). Meiosis is also known as the reductional division. Haploid number of chromosomes found in daughter cells.
In the shoot apical and root apical the embryo is divided by mitotic cell division. The cell of apical meristem and lateral meristem don’t show meiosis division. The mitosis division is also observed in the microspores and anther walls.
In flowering plants, another is the male part of the flower; it has microsporocytes. These are the diploid cells. Microspores are formed in it. These are also known as microspore mother cells or pollen mother cells. They give rise to pollen grains that have a haploid number of chromosomes. This process is called microsporogenesis. After the division of cells microspores are formed. Microspores are called male gametes. From the above information we have found that meiosis is best observed in the microsporocytes.

Hence, the correct answer is option (C).

Note: During the microsporogenesis, each microsporocytes produce four microspores. Microspores are also called as land plant spores that develop into male gametophytes. In angiosperms, female gametophyte is known as megaspores which develop into female gametophytes. The microgametophyte has mainly two cells: the tube cell and the generative cell.
