To stay alive, living things must grow and reproduce.

Human cells divide through mitosis and meiosis.

Mitosis:

It is a division of an equation.

It divides in a 24-hour period.

It happens in somatic or body cells.

The mitosis division produces two daughter cells.

Prophase, Metaphase, Anaphase, and Telophase are the phases of Mitosis.

It has the same set of chromosomes as you do.

Meiosis:

It is a division by reduction.

It happens in germ or sex cells.

Meiosis II and meosis I make up this process.

Prophase I, Meta Phase I, Ana Phase I, and Telo Phase I are all parts of Meiosis I.

Prophase II, Meta II, Ana II, and Tel II are all parts of Meiosis II.

It creates four daughter cells.

It is made up of a partial set of chromosomes.

Option 3 is the correct answer.
