Prokaryotes have no membrane-bound nucleus or organelles. A is incorrect. Plant eukaryotes have a cell wall. B and C are incorrect. All prokaryotes and eukaryotes have a plasma membrane and many ribosomes. Question 2 A A is correct. Chloroplasts have a double outer-membrane, whereas mitochondria have a smooth outer-membrane and a folded inner membrane. B is incorrect. There are no pigments in mitochondria; enzymes are attached to the inner folded membrane. C is incorrect. Both organelles have membranes made of phospholipid and protein. D is incorrect. Both organelles contain ribosomes. Question 3 B B is correct. Vesicles are surrounded by a membrane and carry out a range of activities. A is incorrect. Cytoplasm is the fluid containing the organelles inside the cell membrane. C is incorrect. Lysosomes are a specific type of vesicle with the role of digesting engulfed material. D is incorrect. The nucleolus is an organelle with a specific function that is not surrounded by a membrane. Question 4 D D is correct. By having several different membrane-bound intracellular environments, the cell can function efficiently to carry out all activities optimally. A, B and C are incorrect. None of these are an advantage of membrane-bound compartmentalisation in the cytosol. Question 5 B B is correct. Lipid-soluble molecules can dissolve in the phospholipid bilayer and readily pass through. A is incorrect. Protein molecules are too large to pass through protein channels in the plasma membrane. C is incorrect. Although ions are small, they cannot pass through the bilayer directly, as they are water soluble, and so must pass through the protein channels. D is incorrect. The presence of cholesterol helps to maintain membrane stability, but it does not aid in the membrane acting as a semi-permeable boundary. Question 6 D D is correct. The diagram of method A shows facilitated diffusion and the diagram of method B shows active transport, so the direction of movement in method A is along the concentration gradient, whereas the movement in method B is against the concentration gradient. A is incorrect. Facilitated diffusion does not require energy. B is incorrect. Facilitated diffusion does need carrier protein molecules. C is incorrect. The movement in method B is not through the phospholipid bilayer. Question 7 C C is correct. Absorption of glucose out of the small intestine into the blood is against the concentration gradient, and therefore requires active transport. A is incorrect. Water absorption in a plant’s roots occurs by osmosis. B is incorrect. The loss of water vapour out of the leaves of a plant occurs by diffusion. D is incorrect. Protein hormones are large molecules and would leave the cells by exocytosis. Question 8 A A is correct. In photosynthesis, carbon from the input of carbon dioxide joins with the hydrogen ions from water, using energy to produce the carbohydrate glucose. B is incorrect. Oxygen is not a waste product; plant cells will use it in cellular respiration. C is incorrect. Solar energy is already light energy, so no conversion is needed. D is incor
