HideShow resource information
Mitosis
Cell division that forms two daughter cells each with the same number of chromosomes as the parent cell. It has the exact same genetic information.
1 of 16
What does Mitosis occur for?
Growth, Repair and Asexual Reproduction
2 of 16
Meiosis
It occurs in the testes and ovaries. The cells in these organs divide to produce the gametes (eggs and sperm) for sexual reproduction.

What is Digestion?
It is the breaking down of food so that it is small enough and soluble enough to pass through the wall of the small intestine.
4 of 16

It is the transportation of digested food molecules from the lumen of the gut into the blood.

Pharynx / Oesophagus
Carries food to stomach through muscular contractions - peristalsis
