Cell Specialisation

Plants and animals are multicellular (consist of many cells).  Humans are made up of trillions of cells.  

All eukaryotic organisms contain many different types of cells. Each type of cell is designed to carry out a particular job or function. This is known as CELL SPECIALISM.

Humans are made up of over 220 different types of cells.
