specialised cells

• an organism comprising more than one cell is said to be multicellular
• the process of developing cells that have different functions is called cell differentiation
• differentiation allows an organism to be complex
• large size, cell differentiation and complexity are all benefits of being multicellular
• when an organism is developing, cells become specialised
• when cells develop into different forms, we say that they have become differentiated
• we can say that specialised cells are more efficient in performing special functions than non-specialised cells
