Cellular Growth and Division

​Success Criteria

• Compare unicellular and multicellular organisms

• Recognise that growth is linked to cell division (mitosis)

• Explain the importance of mitosis in living things.

• Describe mitosis as cell division for growth and repair.​

Unicellular organisms

These single cells ​are complete organisms.

​

This cell carries out ​ALL necessary life processes.

​

Includes both ​eukaryotes and prokaryotes.

​Multicellular organisms

Multicellular organisms contain many different types of cells and each type of cell is specialised. This means that each type of cell has a different job to do in the organism.​

​

ONLY eukaryotes​

​Cell Division

All living things grow by making new cells. This process is called cell division.

​

There are 2 types of cell division:

1. mitosis - process of making new body cells

2. meiosis - process of making gametes

​Mitosis

Mitosis is a process where a single cell divides into two identical daughter cells.

​

Mitosis is important in living things for growth and repair.​
