Write briefly the significance of mitosis and meiosis in a multicellular organism.

Solution:

Mitosis and Its Importance:

Mitosis helps a single-cell zygote develop into a fully formed creature.

It aids an organism’s development.
It aids in the healing of worn or injured tissues.
It allows flowering plants to propagate vegetatively.
In some creatures, such as Planaria, it aids regeneration.

The Importance of Meiosis: Meiosis guarantees that the number of chromosomes in gametes becomes haploid. This helps to ensure that each species’ chromosomal number is conserved.
Meiosis allows populations to have more genetic diversity. This happens as a result of crossing over during prophase I.
