Why do humans require mitosis and meiosis?

Answer 1

When mitosis occurs, 2 genetically identical daughter cells are formed. Any guesses why its needed? Its needed for the following:

1. Growth of organs and organisms

2. Repair to damaged tissue

3. Replacement of worn-out cells eg. Red blood cells

Answer 2

Humans need a way to grow and replace old cells. Mitosis is a way for this to happen. Suppose you fall and skin your knee. In order for the skin to grow back in this area, mitosis must occur a great many times.

Answer 3

a cell needs to do mitosis because, for example, if u get a cut on your arm, then your skin cells need to reproduce and help heal your skin.

Answer 4

for growth and tissue repair ( replacement of damaged tissues)

It maintains constant chromosomal number. It also important in sexual reproduction

Answer 5
