| Question | Answer |
| Which cells are 'Ribosome's' in? | Plant and Animal |
| Which cells are 'Mitochondria' in? | Plant and Animal |
| Which cells are 'Cytoplasm' in? | Plant and Animal |
| Which cells are 'Cell Membrane' in? | Plant and Animal |
| Which cells are 'Cell Wall' in? | Plant |
| Which cells are 'Chloroplasts' in? | Plant |
| Which cells are 'Vacuole' in? | Plant |
| What is the function of a 'Vacuole'? | It is filled with cell sap which keeps the cell firm. |
| What is the function of a 'Chloroplasts'? | Absorbs energy to make food by photosynthesis and contains chlorophyll. |
| What is the function of a 'Cell Membrane'? | Controls the passage of substances in and out of the cell. |
| What is the function of a 'Ribosomes'? | Where protein synthesis occurs (Make Protein) |
| What is the function of a 'Nucleus'? | Controls the activities of the cell and contains genetic information. |
| What is the function of a 'Cell Wall'? | Made of cellulose and strengthens the cell, but doesn't protect the cell. |
| What is the function of a 'Cytoplasm'? | Where most of the chemical reactions take place. |
| What is the function of a 'Mitochondria'? | Where aerobic respiration takes place. (Normal respiration, to release energy.) |
| What is a specialised Cell? | Specialised cells are cells where their shape and structure enable them to do a particular job. |
| How is a 'root hair cell' specialised? | It is long and thin to increase the surface area. |
| How is a 'white blood cell' specialised? | It can change shape to engulf bacteria and make antibodies. |
| How is a 'sperm cell' specialised? | Has a tail to swim to the egg, it also has a pointed head and is streamlined. |
| How is a 'Egg (Ovum) cell' specialised? | Contains a large food store. |
| How is a 'muscle cell' specialised? | It forms muscle fibres to contract and relax. |
| How is a 'red blood cell (Biconcave disk)' specialised? | It has a large surface area, for absorbing oxygen. |
| How is a 'Palisade cell' specialised? | Contains lots of chloroplasts for photosynthesis. They are tall and packed closely together. |
| How is a 'Nerve cell (Neurone)' specialised? | It has branches to carry messages and they are long to connect together. |
| How is a 'ciliated epithelial cell' specialised? | It has lots of tiny hairs. |
| How is a 'xylem cell' specialised? | They have strong walls and are hollow. |
| How do you calculate magnification? | Magnification = Image Size / Actual Size |
| Where are stem cells found? | Stem cells are found within organs and some body tissue. The function of them is to repair the tissues in which they are found. |
| What is and 'Embryonic stem cell'? | They are: -found in early embryos -have the potential to turn into any kind of cell. |
| What is an 'Adult stem cell'? | They are: -found in bone marrow -have the potential to turn into certain cell types. |
