Cell Differentation and specialisation

Specialised cells are cells that carry out a specific function.

Cells change in to specialsied = Differentation.

Sperm cells take the male dna to the egg -

• A sperm cell has a tail to help it swim to the egg.
• It has a lot of mitochondria to provide energy for swimming.

Nerve cells carry electrical signals around the body - 

• Nerve cells are long to cover more distance in the body
• They have branches at the end to connect other nerve cells.

Muscle cells contract (shorten) - 

• Muscle cells are long so they have space to contract
• They have lots of mitochondria which provides energy for contacting.
