Question

Differentiate between microsporogenesis and megasporogenesis. Which type of cell division occurs during these events? Name the structures formed at the end of these two events.

Answer 1

Hint: Microsporogenesis is the procedure in which microspore mother cell undergoes meiosis as well as it forms haploid microspore tetrad. It reaches in the pollen sac of anther. Megasporogenesis is the procedure in which the megaspore mother cell undergoes meiosis as well as it forms megaspore in the nucleus region. It reaches in the ovule of the ovary.

Complete answer:Key Differences between Microsporogenesis and Megasporogenesis are explained in the table given below-

Microsporogenesis	Megasporogenesis
1. Arrangement of microspores and generation of male gametophyte is termed as microsporogenesis.2. It happens inside microsporangia or anther.3. Many microspore mother cells are distinguished in a microsporangium.4. All the four cells of the microspore tetrads are useful.	1. Arrangement of megaspores, female gametophyte from megaspore mother cells known as megasporogenesis.2. It exists in the nucellus of the ovule also known as megasporangium.3. Only a single megaspore mother cell is distinguished in a megasporangium.4. Only one of the four cells in the megaspore tetrad proceeds to develop.

The kind of cell division that transpires during these incidents is Meiosis or Reduction district that generates haploid gametes from diploid cells.
The structures constructed at the end of the two events are (1) Microspore or pollen grain at the end of the microsporogenesis process. (2) Megaspore that formulates into female gametophyte or embryo sac at the end of the megasporogenesis process.

Note: Both the method of construction of gametes puts up with so the cell division is meiosis to make gametes half. Microsporogenesis outcomes in the construction of haploid microspore from the diploid microspore mother cell. On the other hand megasporogenesis conclusion in the formation of haploid megaspore from the diploid megaspore mother cell.
