| How do you define cells? | Most basic unit of life that organisms are comprised of. |
| nucleus | Controls cell activities. Contains the genetic material. Involved in replication, transcription & translation. |
| cell membrane | Forms a barrier around the cell. Selective permeability - controls substances pass within the cell from either direction |
| cytoplasm | Liquid-like jelly medium that allows metabolic & cellular activities to occur. |
| golgi apparatus/complex | receives, modifies & packages substances and to be transported glycolipids and glycoproteins synthesised fuses two different food classes together |
| Rough endoplasmic reticulum (ER) | contains ribosomes that is involved in protein production |
| smooth endoplasmic reticulum (ER) | Contains no ribosomes. Synthesises lipids (fat-based molecules e.g. glycerol) |
| ribosomes | Protein molecules that are involved in the synthesis of proteins. Can be found as free flowing ribosomes in the cytoplasm. |
| cell wall (only in plants) | made of cellulose rigid and withstands osmotic (water) pressure from the cell additional protective membrane layer maintains the shape and form of cell |
| chloroplast | organelle involved in photosynthesis converts light energy into chemical energy (carbon storage) contains chlorophyll |
| pigment or molecule found in chloroplasts absorbs sunlight to store carbon | |
| contains cell sap that stores dissolved sugars, mineral ions and other solutes stores food supports turgidity of the cell - waters enter & exit depending on the availability |
