Biology B2 - Cell Organisation

Large Multicellular Organisms are Made Up of Organ Systems 

1) Specialised cells carry out a particular function 

2) this is a process called differentiation 

3) this happens during the develpment of a multicellular organism 

4) these specialised cells form tissues which form organs which form organ tissues 

5) large multicellular organisms (eg squirrels) have different systems for exchanging and transporting materials 

Similar cells are organised into tissues 

- a tissue is a group of cells that work together to carry out a particular function

muscle tissue - contracts to move whatever its attached too 

glandular tissue…
