1) All living things are composed of cells.2) The bodies of living organism are made up

of microscopic units called cell.

3)

Cells are the basic unit ofstructure

andfunctionin living things.4) These living organism are fungi, protista,

plants and animals.

5) New cells are produced from existing cells.
