Multicellular:Organims consisting of many cells:

flower

Cat

Unicellular and multicellular

The number pf cells in the body varies with different organims.

In some lower forms of life [example:euglena,Amobea]the body is formed of a single cell;these organisms are described as unicellular.

In a unicellular organisms all life activites are carries out by this cell internol structures the intracellular structures
