Cell Division

Question 1

Why do cells divide?

Answer 1

To reproduce
To grow
To repair

Question 2

What are the two types of reproduction and what are the differences between them?

Answer 2

Asexual and sexual reproduction

Asexual - producing offspring from only one parent. The offspring are genetically identical to the parent (eg: bacteria).

Sexual - producing offspring by the fusion of two gametes. The offspring has genetic information from both parents (gametes, sometimes called “half cells” only contain half the DNA of a normal cell)

Question 3

Why can’t cells grow bigger for growth instead of dividing?

Answer 3

The cell can’t process certain functions like transportation and the cell has an optimum size. They have to divide in order to grow.

Question 4

What are examples of cells dividing to repair?

Answer 4

Cells divide to heal a broke pan bone

Dead skin cells shed to be replaced by new ones.
