Key points

1. Cells are the basic structural and functional units of an organism.
2. Protoplasm is the living material in a cell. Its composition is unique to each type of cell. It consists of the cytoplasm and nucleus.
3. The cell surface membrane, or plasma membrane, is a selectively permeable membrane that encloses the contents of a cell (the cytoplasm and nucleus).
4. Differentiation is a process that occurs during development, during which a cell becomes specialised for a particular function.
5. A tissue is a group of cells that are specialised for a specific function.
6. An organ is a structure that is composed of different tissues, which together perform a specific function.
