Cell Organelles*
Cell Organelles and Functions
| Question | Answer |
|---|---|
| Mitochondrion (mitochondria) | - Transforms food into ATP in the crista (pl. cristae) |
| Nucleus (nuclei) | - 2 membranes (nuclear envelope) - Nuclear Pores - DNA organised into chromosomes |
| Ribosome | - made of protein and rRNA (ribosome RNA) - 2 subunits; large and small. - makes protein with instructions from the DNA |
| Golgi Apparatus | - flatten membranes; cisterna (pl. cisternae) |
| Vacuole | - single membrane; tonoplast in plants, - fills most of the plant cell; contains sap to keeps cell firm - very small in animal cell; stores food or waste |
| Lysosome | - single membrane that contains digestive enzymes, - digests nutrients, worn out organelles, bacteria (in white blood cells), worn-out cell. |
| Plasma Membrane (Cell Membrane) | - controls what goes in and out of the cell. - made of a phospholipid bilayer with hydrophilic heads and hydrophobic tails |
| Microtubules (Cytoskeleton) | - spirals of protein - structure and support for all the cellular structures - allows it to move because it can break down and rebuild itself |
| Chloroplast (in plant cells) | - 2 membranes - green do to chlorophyll pigment - 20-100 per cell - stack of thylakoids called a granum - photosynthesise (6CO2+6H2O -> C6H2O6+02) |
