Concepts Review
1. The following key terms are associated with the ways in which scientists gather information and conduct investigations. Explain the meaning of each term: [K/U T/I] (a) hypothesis (b) independent variable (c) dependent variable (d) controlled experiment
2. Decide if each statement is true or false. If it is true, copy it directly into your notebook. If it is false, rewrite it to make it true. [K/U] (a) All living things are made up of many cells. (b) Living things grow, reproduce, and repair themselves. (c) Most living things require energy to function. (d) Animals respond to changes in their environment, but plants do not. (e) All organisms perform photosynthesis, but only plants perform cellular respiration.
3. Match each term with correct definition. [K/U] (a) mutualism (b) symbiosis (c) parasitism (d) commensalism
(i) a situation in which two organisms live in close contact and at least one benefits
(ii) a situation in which one organism lives in or on another organism and feeds on that organism
(iii) a situation in which two organisms live in close contact and both benefit
(iv) a situation in which two organisms live in close contact; one benefits and the other is not affected
6. State the function of each of the following: [K/U]
(a) chromosomes
(b) mitochondria
(c) chloroplasts
(d) flagella
(e) DNA
(f) ribosomes
(g) nuclei
7. Compare and contrast the following terms: [K/U]
(a) cell wall and cell membrane
(b) unicellular and multicellular
(c) mitosis and the cell cycle
8. State the function of each of the following:[K/U]
(a) muscle tissue
(b) nervous tissue
(c) vascular tissue
(d) epithelium

Organisms:
tuna
salmonella
slug
mushroom
ant
E. coli
Fern
bread mould
moss
amoeba
yeast
Kingdoms:
Bacteria
Protists
Fungi
Plants
Animals
11. (a) What does the term "micro-organism" mean?
(b) Give one or two examples of micro-organisms.
(c) What invention was necessary for the discovery of these organisms?
(d) How did this invention alter our understanding of all organisms? [K/U]

18. Examine the cells in Figure 1. [K/U T/I A]
(a) Identify each cell as a plant, animal, bacteria, or protist. Give reasons for your choices.
(b) What evidence suggests that some of these organisms have the ability to move?
(c) What evidence suggests that one of these organisms has the ability to produce its own food?
Figure 1
Images: First image is a long solid-like substance, bluish-grey in color with a large horse-shoe shape on top of it; Second image is a small reddish orange oval shape, with long strings attached to the end of it; Third image is multiple almost-round shapes, mostly pink in color, with a dark ring on them; Fourth image is several small round and oval shapes with long strings attached to them, and light green in color.
24. When you use the Internet for research, you often find countless different sources of information.
(a) What criteria do you use to determine if the information is accurate and reliable?
(b) What steps do you take that allow you to use and present this information effectively without plagiarizing? [T/I C]
