They are hard to see so we must use a to see them. 2 The drawings below show parts of three different organ systems. Draw a line from each organ system to its function. Draw only three lines. digestion reproduction movement excretion gas exchange [3] Smart Learning Ltd 2014 Copying permitted for purchasing institution only. SMART SCIENCE 1

2 Biology Term 1 Biology Term 1 3 The diagram shows a cell from a leaf. On the diagram, use the words from the list to label the parts A C: nucleus cell wall cell membrane cytoplasm vacuole [3] 4 Muscles work by contraction. This means they can only and never. 5 Put a tick in the correct boxes in the table below to show which parts are present in the cells listed: Muscle cell Bacterial cell Cytoplasm Nucleus Cell wall Chloroplasts [4] 6 The cells in plants have cell walls as well as cell membranes. What is the function of the cell wall? [1] 2 TEACHER S HANDBOOK 1 Smart Learning Ltd 2014 Copying permitted for purchasing institution only.

3 Biology Term 1 7 Which two of the following statements about diffusion in a cell are true? The surface area of the cell membrane controls how many molecules can enter at once. Particles diffuse at a slower speed in large cells than in small cells. Diffusion happens more slowly in large cells because of the smaller surface area to volume ratio of the membrane. The surface area of a cell membrane increases at the same rate as its volume. Biology Term 1 8 The diagram below shows bones and muscles of the human arm. The biceps and triceps are muscles that contract to move the bones of the lower arm. (i) What do the biceps and triceps do to move the arm in the direction shown by the arrow? Tick the correct box. The biceps and the triceps relax at the same time. The biceps relaxes and the triceps contracts. The biceps contracts and the triceps relaxes. The biceps and the triceps contract at the same time.

4 Biology Term 1 Biology Term 1 (ii) Ligaments hold bones together at a joint. Ligaments can stretch. Why must ligaments be able to stretch? 9 The diagram shows a woman s reproductive system just before fertilisation takes place. The fallopian tube is lined with ciliated cells. A ciliated cell and a are drawn in more detail. [3] (i) Describe the function of the ciliated cells lining the fallopian tube. (ii) Sperm use their tails to swim to the egg so that fertilisation can take place. State one other way in which a sperm is adapted for fertilisation. Explain your answer. 4 TEACHER S HANDBOOK 1 Smart Learning Ltd 2014 Copying permitted for purchasing institution only.

5 Biology Term 1 10 A scientist was studying a series of different cells. The diagrams are below. [8] Biology Term 1 The values for cell B for surface area and volume have been calculated for you. Complete the table for cell A as follows. (i) Calculate the surface area of cell A. Show your working and the units then add your answer to the table below. (ii) Calculate the volume of cell A. Show your working and the units then add your answer to the table below. (iii) Calculate the surface area to volume ratio for both of the cells. Add your answers to the table below. Cell Surface area (mm 2 ) Volume (mm 3 ) Surface area : volume ratio A B (iv) The cells all receive nutrients from the blood. Explain which cell would receive nutrients fastest.

7 Biology Term 1 12 The drawing shows a group of three cells. Draw an outline showing how the cells would appear under the microscope if the section A A was cut thinly and mounted on a slide. Biology Term 1 Smart Learning Ltd 2014 Copying permitted for purchasing institution only. SMART SCIENCE 7

8 Biology Term 1 Biology Term 1 Six-mark question When answering this question you need to: use good English, paying attention to spelling and punctuation organise your information clearly with an introduction, an explanation and a conclusion (you can use a table for the explanation if you prefer) ensure that you use the correct scientific terms. Read the following information and complete the task: The diagram below shows a microscope, a slide and cover slip, an onion, methylene blue stain, a scalpel and forceps. A student wants to set up a microscope slide to observe an onion cell. Describe and explain how she should go about it using the apparatus in the diagram. You should include: how to prepare the slide how to use the microscope to focus the image identifying and reducing the risks of the investigation.
