| Question | Answer |
| Identify the functions of the nucleus. | Controls cell activity Contains genetic material. |
| What is a type of eukaryotic cell ? | animal or plant cell. |
| what is the function of the mitochondria? | an organelle where aerobic respiration takes place. |
| what is an organelle? | Specialised structures found within a living cell. |
| What is the function of a chloroplast? | a plant organelle where photosynthesis takes place. |
| What is the function of ribosomes? | Protein synthesis. |
| How can you tell the difference between the RER and the SER? | RER is embedded with ribosomes SER has no ribosomes. |
| What is the structure of the golgi apparatus? | A stack of membrane bound flattened sacks. |
| What is the function of the nucleolus ? | Makes RNA and ribosomes. |
| What is the function of the cytoplasm? | The place where metabolic reactions take place. |
| What is the structure of the cell membrane? | a phospholipid bilayer, embedded with proteins. |
| What is the function of vesicles? | To transport materials around and out the cell. |
| What are lysosomes? | Specialised vesicles that contain digestive enzymes that break down waste material from inside the cell. |
| What are centrioles? | They form spindles that pull apart chromosomes during cell division. |
| What is exocytosis? | The process of vesicles fusing with the plasma membrane and secreting it's contents. |
| What is the cell wall made of? | Cellulose. |
| What is the function of the cell wall? | Protects and supports each cell and the whole plant. |
| What is a vacuole? | Membrane bound sac containing cell sap that maintain a turgid structure to the cell. |
| What is the tonoplast? | It is the partially permeable membrane of the vacuole. |
| What is an amyloplast? | A double membrane-bound sac containing starch granules. |
| What is the function of the amyloplast? | Responsible for the synthesis and storage of starch granules. |
| What is a plasmodesmata? | Channels within the cell wall of plant cells which enables transport and communication between plant cells. |
| What are the pits inside plant cells? | Pores in the cell walls of the xylem that allows water to enter and leave the xylem vessels. |
