Cell Specialisation in Animals

Cell Specialisation in Animals. 

What happens when a cell differentiates?                                                                                         It becomes a different type of body cell. 

Cell differentiation is a process where a cell gains new sub - cellular structures in order to perform a specific function. When this happens the cell becoms specialised.

Embryos

• Cell differentiation happens during an organism's development.
• Organisms start as one cell.
• These cells divide to form embryos that differentiate (specialise) to produce cells that can perform all of the body's functions. 

Plants                                                                                                                                              

• Many plant cells keep their ability to differentiate throughout their life.
• Because of this, plants are always able to create new tissues (matter that animals and plants are made from). 

Adult Animals

• Cell differentiate is rare in mature (adult) animals.
• Their cells mostly divide (one cell splits to create two cells) in order to replace cells and repair tissues.
• New tissues are rarley created. 

Cell differentiation is rare in mature animals. Their cells mostly divide to replace cells and repair damaged tissues.

Sperm Cells

The main function of a sperm cell is to fertilise the egg cells
