| What is the function of the Smooth Endoplasmic Reticulum (ER) | Lipid metabolism and specialised functions specific to liver and muscle cells |
| What is the function of the Golgi complex | Sorting and tagging proteins for distribution and secretion. can modify: attach lipids or carbohydrate, break down into smaller hormones |
| What do Lysosomes do | Lysosomes contain digestive enzymes (acid hydrolyses) to break down foreign material, cells or organelles. |
| What is the nucleus? | Control centre of the cell. Contains all the genetic material/instructions on how to function. |
| What is the cytoskeleton? | network of protein fibres involved in: movement, structure and tensile strength |
| Three types of cellular extension and the function of each | Flagella - movement of the cell (sperm) Microvilli - increase surface area/absorbtion Cilia - move substance across the surface |
