The cell cycle is the order in which body parts grow.

The cell cycle is the life cycle of a cell, from its birth until its death.

The cell cycle pulls chromosomes apart during mitosis.

The cell cycle controls when cells divide.

...will divide and start the cell cycle over again.

Spiders are trapping prey in a web

Chromosomes are being separated to opposite sides of a cell

A sperm cell is fertilizing the egg cell in a flower

Chromosomes are being lined up

Cells begin to perform fertilization.

Checkpoint proteins prevent a cell from continuing the cell cycle.

A hormone tells one cell to die for every new cell that is born

Cells get smaller

Without growth hormone, the child will not be able to absorb nutrients.

Without growth hormone, the child's cells will get too big to divide.

Without growth hormone, checkpoint proteins will stop the child's cells from dividing.

Without growth hormone, the child's blood sugar will get too high and they will become dehydrated.

Number of chromosomes double.

Cell makes RNA.

Cell changes shape.

Cell makes proteins.
