- Specialised Cells
- As an organism develops, cells differentiate to form different types of cells. They become specialised
- Most types of animal cells differentiate at an early age
- Plant cells can differentiate throughout their whole life
- As a cell differentiates:
- It may change shape
- Different sun-cellular structures develop to let it carry out a specific function
- Specialised cells in animals
- Sperm
- Function
- To fertile an egg cell
- Adaptions
- Long tails with muscle like proteins to swim towards egg
- Full of mitochondria
- A large nucleus containing genetic information to be passed on
- Acrosome containing digestive enzymes to breaking down the outer layers of the egg cell
- Function
- Nerve cells
- Function
- Carry electrical impulses around the body
- Adaptions
- Have lots of dendrites to connect to other nerve cells
- Can get up to 25m long
- Use chemicals to pass impulses to another cell
- Function
- Muscle cells
- Function
- Proves the bones of a skeleton
- Adaptions
- Contains special proteins that can slide over each other making fibres contract
- Contain many mitochondria to transfer energy needed for the chemical reactions to contract cells
- Function
- Sperm
