(e) Where in a plant would you find a cell like the one in the diagram? Tick the correct box. in the centre of a root in the lower surface of a leaf near the upper surface of a leaf near the surface of a root Maximum 6 marks Page 2 of 17
3 Q2. The diagram below shows a single-cell organism called Chlamydomonas. It lives in pond water. Use the information in the diagram to help you answer the questions below. (a) Give two features of Chlamydomonas which show that it is more like a plant cell than an animal cell (b) Chlamydomonas makes a sugar called glucose. (i) Give the name of the process in which Chlamydomonas makes glucose. (ii) Chlamydomonas produces starch grains from glucose. Suggest what will happen to the number of starch grains in the cell if Chlamydomonas is kept in the dark. Page 3 of 17
4 (c) The diagram below shows another single-cell organism called Amoeba. It also lives in pond water. Amoeba traps a Chlamydomonas and digests it. not to scale Starch is a carbohydrate. Amoeba's digestive enzymes break down the starch in the Chlamydomonas. Suggest what substance is produced from the starch and what it is used for Maximum 6 marks Q3. A scientist looked at a sample of fresh blood under a microscope. She produced the following drawings of what she saw. Two types of white blood cells are shown in the drawings. Page 4 of 17
5 (a) Give two ways in which white blood cells destroy disease-causing micro-organisms (b) (i) Red blood cells transport oxygen. They contain a chemical which combines with oxygen from the lungs. Give the name of the product formed when oxygen combines with this chemical.... (ii) Blood plasma transports glucose. Give the names of two other substances or types of substances which are transported in the plasma (c) The scientist added a drop of distilled water to some fresh blood on a microscope slide. The red blood cells absorbed water. Some of them swelled and burst. She then looked at onion cells under a microscope. She added a drop of distilled water to the slide. None of the cells burst. What part of an onion cell prevents it from bursting?... Maximum 6 marks Q4. The drawings show some plant and animal cells. Each cell has a different function. not to scale Page 5 of 17

Complete the word equation for photosynthesis. water + carbon dioxide... + oxygen (b) Jonathan studied a blackberry plant growing in a shady place and a blackberry plant growing in a sunny place. (i) Jonathan found that the plant in the shady place had larger leaves. Why is it an advantage for plants in the shade to have leaves with a large surface area? Page 6 of 17
7 (ii) Both blackberry plants had green leaves. What part of the leaf cells makes the leaf green?... (c) The diagram below shows a cell from a leaf of a blackberry plant.
