cell organisation

large multicellular organisms are made up of organ systems

• cells are the basic building blocks that make up all living organisns
• specialised cell carry out a particular function 
• the process by which cells become specialised for a particular job is called differentiation. diifrentiation occurs during the development of a multicellular organism
• these specialised cells form tissues which forms organs which form organ systems 
• large multicellular organisms (eg squirrels) have diffrent systems inside of them for exchanging and transporting materials 

similar cells are organised into tissues 

A tissue is a group of similar cells that work together to carry out particular functions it can include more than…
