| Question | Answer |
| How do we know if something is living? | If they do everything in MRS GRENC |
| What do the letter in MRS GRENC stand for? | Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition & Control of internal environment. |
| Definition: Movement | Moving whole or part of body |
| Definition: Respiration | Chemical reaction releasing energy from food |
| Definition: Sensitivity | Responding to stimuli in the environment |
| Definition: Growth | Increasing in size or mass. |
| Definition: Reproduction | Producing offspring sexually or asexually. |
| Definition: Excretion | Getting rid of toxic waste products made in the cells. |
| Definition:Nutrition | Obtaining food. |
| Definition: Control of internal environment. | Maintaining constant conditions in and around the cells. |
| What is a cell wall? | Fully permeable and helps maintain cell shape. |
| What organisms have a cell wall? | Plant, Fungi, Bacteria |
| What is a cell membrane? | Controls what molecules leave and enter the cell. |
| What organisms have a cell membrane? | Animal, bacteria, plant & fungi |
| What is cytoplasm? | Site of most chemical reactions. |
| What organisms have cytoplasm? | Fungi, animal, plant & bacteria. |
| What is a nucleus? | Controls cell activity and contains hereditary material. |
| What organisms have a nucleus? | Animal, plant & fungi. |
| What are chloroplasts? | Site of photosynthesis. |
| What organisms have chloroplasts? | Plants. |
| What are mitochondria? | Site of aerobic respiration. |
| What organisms have mitochondria? | Animal, plant & fungi. |
| What is a vacuole? | Contains cell sap & helps maintain cell shape. |
| What organisms have a vacuole? | Plant & fungi. |
| What are ribosomes? | Organelle making protein. |
| What organisms have ribosomes? | Plant, animal, fungi & bacteria. |
| Name the 6 kingdoms | Animal, Plant, Bacteria, Fungi, Virus & Protoctists. |
| How do animal cells store carbohydrates? | As glycogen. |
| How do plant cells store carbohydrates? | As starch or sucrose. |
| What are plant cell walls made of? | Cellulose. |
| What are fungi cell walls made of? | Chitin. |
| How do fungi store carbohydrates? | As glycogen. |
| What is bacteria cell wall made of? | Sugar & Protein. |
| Bacteria cells don't have a nucleus so where is their hereditary material? | It is stored in a single strand of DNA in the centre of the cell. |
| Why aren't virus considered living? | They don't do MRS GRENC, but they can only 'live' and reproduce inside other organisms. |
| What does the term parasitic mean? | Something that can only live/reproduce inside another organism. |
| What is the smallest of the kingdoms? | Virus |
| What is a pathogen? | A disease causing micro-organism. |
| What kingdoms can pathogens come from? | Bacteria, fungi, virus or protoctist. |
| 2 examples of a viral disease. | Aids and common cold. |
| 2 examples of a fungal disease. | Athletes foot and thrush. |
| 2 examples of a bacterial disease. | Salmonella and e-coli. |
| 1 example of protoctist disease. | Malaria. |
| Examples of specialised animal cells: | Red blood cell and muscle cell. |
| Examples of specialised plant cells: | Root hair cells & palisade cells. |
