1 For each statement, write true or false If the answer is false, write WHY it is false

2 1 All prokaryotes and eukaryotes store hereditary information (also known as DNA)

3 2 All prokaryotes and eukaryotes have organelles that help control cell processes

4 3 All prokaryotes and eukaryotes use the process of cellular respiration to release energy

5 4 All prokaryotes and eukaryotes move

6 5 Bacteria are an example of prokaryotes

7 6 Prokaryotes are smaller than eukaryotes because they don’t have a nucleus or organelles

8 7 Prokaryotes and eukaryotes both have a nucleus

9 8 Prokaryotes and eukaryotes both have cell membranes

10 9 All prokaryotes and all eukaryotes have a cell wall

11 10 The four types of macromolecules are water, carbohydrates, proteins, and nucleic acid s

12 11 The reason carbon is an ideal central element for macromolecules is that it can form large, diverse molecules

13 12 Enzymes are an example of a carbohydrate

14 13 Carbohydrates store information

15 14 Carbohydrates store energy for short-term use

16 15 Carbohydrates store energy for long-term use

17 16 The role of an enzyme is to speed up a chemical reaction

18 17 Enzymes provide energy for reactions

19 18 pH and temperature can affect enzymes by changing the enzyme’s shape

20 19 If you were measuring the volume of a liquid, you would use units like meter or millimeter

21 20 Photosynthesis occurs in plants and animals

22 21 Cellular respiration occurs in plants and animals

23 22 Photosynthesis and cellular respiration both transform energy

24 23 Photosynthesis and cellular respiration both require light energy

25 24 When proteins need energy to move something across the membrane, they use ADP as an energy source

26 25 When molecules like carbon dioxide or oxygen move across a cell membrane, this is called osmosis

27 26 When molecules move freely across a cell membrane, that is because there is a concentration gradient or difference in concentrations

28 27 When a cell is placed in a hypertonic solution, water will leave the cell

29 28 The rough endoplasmic reticulum makes nucleic acids

30 29 Old cell materials are broken down by enzymes stored inside of lysosomes

31 30 The golgi body packages proteins into vesicles

32 31 The rough endoplasmic reticulum helps to determine which proteins to synthesize

33 32 Sweating is an example of homeostasis

34 33 Every hypothesis must be able to be tested using research or experiments

35 34 Every hypothesis should test multiple variables

36 35 All living things move

37 36 All living things breathe in oxygen

38 37 All living things are made of many cells

39 38 All living things use energy

40 39 A neutral solution has a pH of 10

41 40 Basic solutions have a pH of less than 7

42 41 Water is an acid

43 42 Water is a non-polar molecule

44 43 Water has a low heat capacity

45 44 Water is both cohesive (sticks to other water molecules) and adhesive (sticks to different molecules)

46 45 In a chemical reaction, the materials that enter a reaction are called products

47 46 Photosynthesis occurs in the chloroplast

48 47 Animal cells have chloroplasts

49 48 The part of a cell that controls the cell’s activities is called the nucleus

50 49 Energy is released when ADP is converted to ATP

51 50 Cells are the basic unit of life

52 51 Cellular respiration converts oxygen and glucose into carbon dioxide and water

53 52 During photosynthesis, plants absorb oxygen and produce carbon dioxide

54 53 Proteins are long chains of amino acids

55 54 Carbohydrates are made of carbon, hydrogen, and nitrogen

56 55 Photosynthesis requires light

57 56 Even if plants aren’t in the light, they still use the process of photosynthesis

58 57 If a hypothesis is rejected, that means it was not correct.

59 58 Aquatic plants use photosynthesis just like plants that live on land

60 59 Snails do not use oxygen for cellular respiration because they live under water

61 60 In an experiment, the variable that is different for each experimental group is called the independent variable
