Q2. The diagram shows an animal cell. (a) (i) Name structures A and B by choosing the correct words from the box. cell membrane cell wall cytoplasm nucleus vacuole Structure A... Structure B... (2) (ii) Which structure named in the box controls the passage of substances in and out of the cell?... () Distance P to Q on the diagram is the diameter of the cell. This distance was measured on three cells using a microscope. The results were as follows: cell : 63 micrometres cell 2: 78 micrometres cell 3: 69 micrometres Calculate the average diameter of these cells. Show clearly how you work out your final answer....... Average diameter =... micrometres (2) (Total 5 marks) Page 3 of 8
Q3. The diagram shows a yeast cell. Label structures A and B on the diagram. Choose your answers from the list in the box. cell membrane cell wall nucleus vacuole (Total 2 marks) Q4. The diagram shows a cell from the lining of the lung. This cell is specialised to allow gases to pass through quickly. (a) Use words from the box to label structures A, B and C. cell membrane chloroplast cytoplasm mitochondria nucleus (3) Page 4 of 8
(i) Which feature of this cell allows oxygen to pass through quickly? Put a tick ( ) in the box next to your choice. It is thin. It has a large nucleus. It has many mitochondria. () (ii) Complete the sentence by drawing a ring around the correct answer in the box. Oxygen passes through this cell by diffusion osmosis respiration () (Total 5 marks) Q5. The diagram shows a group of muscle cells from the wall of the intestine. (a) On the diagram, use words from the box to name the structures labelled A, B and C. cell membrane cell wall chloroplast cytoplasm nucleus (3) Page 5 of 8
How are these muscle cells adapted to release a lot of energy?......... (2) (Total 5 marks) Q6. (a) The diagrams show cells containing and surrounded by oxygen molecules. Oxygen can move into cells or out of cells. Into which cell, A, B, C or D, will oxygen move the fastest? Write your answer, A, B, C or D, in the box. () Draw a ring around the correct word to complete each sentence. diffusion (i) Oxygen is taken into cells by the process of osmosis. respiration () Page 6 of 8
breathing (ii) Cells need oxygen for photosynthesis. respiration () membranes (iii) The parts of cells that use up the most oxygen are the mitochondria. nuclei () diffusion (iv) Some cells produce oxygen in the process of photosynthesis. respiration () (Total 5 marks) Q7. Diagram shows a cell from a leaf. Diagram Page 7 of 8
(a) How is the leaf cell specialised to carry out photosynthesis? Tick ( ) one box. It has a permanent vacuole. It has many chloroplasts. It has cytoplasm. It has many mitochondria. () Diagram 2 shows another type of plant cell. Diagram 2 Give two ways in which this cell is different from an animal cell....... 2...... (2) (Total 3 marks) Q8. This question is about cells. (a) (i) The diagram shows a sperm cell. Page 8 of 8
Use words from the box to label parts A and B. cell membrane cytoplasm nucleus (2) (ii) The diagram shows a cell from a leaf. Give the letters of two parts of the leaf cell which would not be found in a sperm cell. and. () Sperm cells have many mitochondria. Why do sperm cells need many mitochondria? Tick ( ) one box. Sperm cells are involved in fertilisation. Sperm cells are produced in very large numbers. Sperm cells need a lot of energy to swim. () (Total 4 marks) Page 9 of 8

Draw one line from each structure in List A to the correct information about the structure in List B. List A Structure List B Information (4) Give two differences between an animal cell and the cell of a bacterium.... 2... (2) Page of 8
(c) The diagrams show cells containing and surrounded by oxygen molecules. Oxygen can move into cells or out of cells. Into which cell, A, B, C or D, will oxygen move the fastest? Write the correct letter, A, B, C or D, in the box. () (d) Complete the following sentence. Oxygen is taken into the cell by the process of... () (Total 8 marks) Page 2 of 8
