Why do we need mitosis?
A
Cell growth
B
To replace cells
C
Both reasons
D
Neither
Explanation: 

Detailed explanation-1: -Mitosis is crucial to this process. Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.

Detailed explanation-2: -This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development. Together, they provide the cellular basis for healthy growth and sexual reproduction.

Detailed explanation-3: -Mitosis is required for growth, repair, and asexual reproduction. It plays an important role in the development of an organism. In single-celled organisms, mitosis is seen as the process of asexual reproduction. It also helps in the replacement of damaged tissues.

Detailed explanation-4: -Growth of the organism. An adult human being is made up of billions of cells and all cells have the same genetic component. Repair. Replacement. In plants, vegetative multiplication is by mitosis (asexual reproduction)
