3 Quiz 3: Microscopy & Cells. A 1. Label structures A-D from the diagram. (2 marks). 2. Draw an equation triangle for calculating magnification from the actual size of a specimen and the image size. (2 marks). 3. Calculate the image size of an object when it has been magnified x100 and the real size is 3µm. (2 marks). 4. What stain is used when preparing a slide with onion tissue. (1 mark). 5.

List the an argument for and against stem cell research. (2 marks). 4. Give an adaptation of each specialised cell and the reason for it: (5 marks). a) Root Hair Cell b) Sperm c) Muscle Cell d) Xylem e) Nerve Cell f) Phloem 5

6 Quiz 6: Diffusion, Osmosis and Active Transport 1. Give an adaptation of each specialised cell and the reason for it: (2 marks). a) Root Hair Cell b) Muscle Cell 2. Define Osmosis: (3 marks for all correct) Osmosis is the movement of molecules across a partially permeable from a region of water concentration to a region of water concentration. 3. When a cell is firm due to water moving into a cell we call it (1 mark) 4. When the cell is floppy as water has moved out we call it (1 mark). 5. Which process requires energy (ATP); diffusion, osmosis or active transport? (1 mark). 6. Which process moves against a concentration gradient; diffusion, osmosis or active transport? (1 mark). 7. Give an example of where diffusion happens in the human body. (1 mark). 6

7 Quiz 7a: Mitosis 1. Which process moves along a concentration gradient; diffusion or active transport? (1 mark). 2. Give an example of where diffusion happens in the human body. (1 mark). 3. What do we call the cell we start with at the beginning of mitosis? (1 mark). 4. Sequence Mitosis. (2 marks) A Spindle fibres pull apart the duplicated chromosomes. B Chromosomes duplicate in the original cell (copies made). C Chromosomes line up in the centre on spindle fibres. D A new nuclei is formed around the chromosomes. E The cell divides to form two daughter cells. 7

8 Quiz 7b: Mitosis 5. How many pairs of chromosomes does a human have? (1 mark). 6. Where is DNA located in a cell? (1 mark). 7.
