Wordlists
| Question | Answer |
|---|---|
| Absorb | Soak up. |
| Function | Something's job. |
| Mineral Salt | Chemical found in soil that plants need for healthy growth. |
| Nitrate | Mineral salt that plants need to make proteins. |
| Phloem Tube | Tube made from chains of living phloem cells. Carries glucose and other soluble substances up and down the plant. |
| Root Hair Cell | Cell found in roots. The root hair has a large surface are to help the cell absorb water quickly. |
| Wilting | When a plant does not have enough water and droops. |
| Xylem Tubes | Tube made from chains of dead, hollow xylem cells. Carries water and dissolved mineral salts up a plant. |
| Global Warming | The process of the earth's atmosphere warming up. It is partly caused by an increase in carbon dioxide in the air. |
| Methane | The gas that is 'natural gas'. Also formed in large amounts in the digestive systems of cows. Methane absorbs heat and so helps global warming. |
| Aerobic Respiration | Chemical reaction that releases energy from glucose. It uses up oxygen and produces carbon dioxide and water. |
| Biomass | The mass of material(expect water) that makes up an organism. |
| Chlorophyll | Green substance found inside chloroplasts. It absorbs light. |
| Glucose | Type of sugar made during photosynthesis. |
| Photosynthesis | Chemical reaction that plants use to make their own food. It needs light to work. Carbon dioxide and water are reactants and glucose and oxygen are the products. |
| Raw Material | Something used up in the chemical reaction. Also called reactant. |
| Reactant | Something used up in the chemical reaction. Also called raw material. |
| Phloem Tube | Tube made from chains of living phloem cells. Carries glucose and other soluble substances up and down the plant. |
| Product | Something made in a chemical reaction. |
| Starch | Insoluble carbohydrate made from glucose and used as a storage material in plants. |
| Word Equation | Simple way of showing what happens in a chemical reaction |
| Adapted | When something has a particular shape to help it do a function(job). A root hair cell has a shape that helps it absorb water and is said to be 'adapted to its function'. |
| Amino Acids | The building blocks of protein. |
| Cellulose | A substance used to make cell walls. |
| Chloroplast | Green disc containing chlorophyll. Found in plant cells. Where glucose is made by photosynthesis |
| Diffusion | The random movement of particles from where there are a lot of them to where there are fewer of them. |
| Fat | Substance needed by living things to make cell membranes. Our bodies also use fats as a store of energy and to keep warm. |
| Guard Cells | Cells which open and close the stomata. |
| Oil | Liquid fat, often found in nuts and seeds. |
| Palisade Cells | Cells found in leaves, containing many chloroplasts. |
| Protein | A substance made from amino acids. Proteins are needed for growth and repair. |
| Stoma | Singular of stomata. |
| Stomata | Small holes on the underside of leaves which let gases into and out of the leaf. |
