A tissue is a group of specialised cells that have the same structure and carry out a particular function.

 

Cell specialisation occurs after cell division where the newly produced cells are structurally altered to allow them to carry out their specific functions.

​

Types of specialised cells include:

• Red blood cells

• Neurons (nerve cells)

• Muscle cells

​

There are four types of tissues:

• Epithelial

• Connective

• Muscular

• Nervous
