Which part: a) brings an object into focus at low or medium power? _________________________ b) supplies the light needed to view the slide? _________________________________ 2. What is the magnification of an object if you use a 4x eyepiece lens with a low-power objective lens? 3. List five characteristics of living things. Give an example for each characteristic. 4. What is the difference between a unicellular and a multicellular organism? 5. What are examples of non-living things that are able to reproduce? Section 1.2 6. What are three differences between animal and plant cells? 1. 2. 3. 7. What are the three parts of Cell Theory? 8. What are: a) prokaryotic cells? b) eukaryotic cells? 9.

If the concentration of water outside a cell is higher than it is inside a cell, in which direction will water move? 13. Identify the term! There are only four terms, so don’t be afraid to repeat. a) refers to the amount of a substance in a given space. b) is the movement of particles from an area of higher concentration to an area of lower concentration. a) b) c) allows some materials to pass through it but keeps other materials out. c) d) is the diffusion of water molecules through a selectively permeable membrane. d) e) moves wastes from inside a cell to outside a cell. e) f) can be compared to a window screen. f) g) happens when water particles move from a place where their concentration is higher to a place where their concentration is lower. g) h) is the process by which oxygen is moved into a cell. i) is the process by which carbon dioxide is moved out of a cell. h) i) 14. Explain what is happening here. Use the terms “diffusion”, “concentration”, and “semipermeable membrane” in your answers. a) a) b) b) c) c) 15. Describe and explain a situation where diffusion takes place. Use the words, “particles”, and “diffusion”.
