Cell specialisation and organisation

• Examples of specialised cells include sperm cells, dendritic cells and muscle cells
• Cell differentiation is a process through which a cell undergoes changes in gene expression to become a more specific type of cell
• Cell = membrane bound structure containing biomolecules such as nucleic acids, organelles and polysaccharides
• Tissue = a group of similar specialised cells that work together to carry out a particular function
• Organ = combination of different tissues working together to carry out a variety of functions
