| Question | Answer |
| (defintion of) Photosynthesis | The production of complex molecules containing energy from simple molecules. |
| How is water uptaken by a plant? | Through it's roots. |
| How is sunlight absorbed by plants? | By a green pigment; called chlorophyll, found in the chloroplasts of plants. |
| Word eq for photosynthesis. | Carbon dioxide + Water [using chlorophyll and sunlight] = Glucose + Oxygen. |
| Symbol eq for photosynthsis. | 6\(CO_2\) + 6\(H_2O\) [using chlorophyll and sunlight] = \(C_6\)\(H_12\)\(O_6\) |
| Where is starch stored in a plant? | In the roots. |
| Which ions are required for photosynthesis? | Nitrate and protein ions. |
| How would a plant recieve magnesium ions? | They are absorbed from the soil. |
| How would a plant recieve nitrate ions? | Absorbed from the soil or added as fertiliser. |
| What are nitrate ions required for? | They help build up amino acids to build protein, which build protein. |
| What are magnesium ions required for? | For the manufacture of chlorophyll. |
| What happens when there is a lack of these nutrients? | A lack of these nutrients causes yellowing in green parts of the plant. |
| What is \(C_6\)\(H_12\)\(O_6\) used for? | Glucose - sugar for respiration. |
| What is the glucose converted to? | Sucrose - stored in fruits Starch - for storage in seeds, leaves and roots Cellulose - for cell walls Lipids/Oil - for storage in seeds |
| What conditions are required for starch production? | Needs carbon dioxide Needs light Needs chlorophyll in leaves |
| What does a plant need to photosynthesise? | Carbon dioxide, water, light and chlorophyll (the production of chlorophyll needs magnesium ions.) |
