(1) Differentiate between microsporogenesis and megasporogenesis. (2) Which type of cell division occurs during these events? (3) Name the structures formed at the end of these two events.

(2) Meiosis or reduction division, which produces haploid gametes from diploid cells, is the type of cell division that takes place during these occurrences.

Features of diploid cells:

1. Have two sets of chromosomes, whereas haploid cells only have one set.
2. They are depicted as 2n and vary depending on the species.
3. They are identified by this chromosome number inside the cell’s nucleus.
4. The body’s diploid somatic cells have a somatic character.
5. Through the process of mitosis, diploid cells replicate and maintain the same number of chromosomes by making a copy of each chromosome and dividing their DNA equally among their daughter cells.

(3) The buildings that were built following the two occurrences are

• A pollen grain or pollen grain following the completion of microsporogenesis.
• Megaspore, at the conclusion of the megasporogenesis process, forms into a female gametophyte or embryo sac.

Summary:

(1) Differentiate between microsporogenesis and megasporogenesis. (2) Which type of cell division occurs during these events? (3) Name the structures formed at the end of these two events.

(1) Megasporogenesis is the organisation of megaspores from the mother cell, whereas microsporogenesis is the generation of microspores by meiotic division.

(2) Reduction or meiosis, which produces haploid gametes from diploid cells, is a type of cell division that takes place in certain instances.

(3) The structures created at the conclusion of these two processes are microspores and megaspores.
