week 2 Cells
Cards in this deck (10)
- 1What is an Organelle?a specialised structure inside a cell that has a specific role in cell activity.
- 2What organelle produces ATP?Mitochrondria (Mitochrondrion singular)
- 3What is the function of Rough Endoplasmic Reticulum (ER)?Rough ER and attached ribosomes synthesise proteins
- 4What is the function of the Smooth Endoplasmic Reticulum (ER)Lipid metabolism and specialised functions specific to liver and muscle cells
- 5What is the function of the Golgi complexSorting and tagging proteins for distribution and secretion.
can modify: attach lipids or carbohydrate, break down into smaller hormones - 6What do Lysosomes doLysosomes contain digestive enzymes (acid hydrolyses) to break down foreign material, cells or organelles.
- 7What is the nucleus?Control centre of the cell. Contains all the genetic material/instructions on how to function.
- 8What is the cytoskeleton?network of protein fibres involved in: movement, structure and tensile strength
- 9Three types of cellular extension and the function of eachFlagella - movement of the cell (sperm)
Microvilli - increase surface area/absorbtion
Cilia - move substance across the surface - 10Why does cell diversity occur?due to each cell having different numbers
