2 To function most efficiently, a cell must be Small in size. Why? 2

3 As cell size increases, the surface-area-to-volume ratio decreases. 3

4 The size to which a cell can grow is limited by its surface area. 4

5 Surface area is an important factor in limiting cell growth because the cell may become too large to take in enough food and to remove enough wastes. 5

6 When the volume of a cell increases, its surface area increases at a slower rate. 6

7 The smallest units of life are cells 7

8 A microscope with a 4x objective lens and a 20x ocular lens produces a total magnification of 80x 8

9 Fuzzy images viewed with a microscope may be due to poor resolution. 9

10 A cell that requires a lot of energy might contain large numbers of mitochondria. 10

11 The image produced by a microscope is called a micrograph. 11

12 The metric system of measurement is based on powers of 10. 12

13 Only eukaryotic cells have membrane-bound organelles. 13

14 A structure within a eukaryotic cell that performs a specific function is called a(n) organelle. 14

15 The packaging and distribution center of the cell is the Golgi apparatus. 15

16 In a cell, proteins are made on the ribosomes. 16

17 Plant cells have a large membrane-bound space in which water, waste products, and nutrients can be stored. This space is called the vacuole. 17

18 This term refers to: surrounds cell membrane and provides support cell wall 18

19 The double membrane surrounding the nucleus is called the nuclear envelope. 19

20 Phospholipids are molecules that channel proteins. 20

21 Which type of molecule forms a lipid bilayer within a cell membrane? phospholipid 21

22 This term refers to: single celled organisms that lacks a nucleus and other internal components prokaryote 22

23 system of internal membranes that move proteins and other substances throughout the cell endoplasmic reticulum 23

24 in plants, organelles that use light to make organic compounds chloroplasts 24

25 Smooth ER lacks ribosomes 25

26 True of false: Chloroplasts have DNA that is different from nuclear DNA. true 26

27 True of false: As a cell gets larger, its surface-area-to- volume ratio decreases. true 27

28 True of false: A phospholipid is a lipid made of a phosphate group and two fatty acids. true 28

29 True of false: Ribosomes are the sites of ATP production. false 29

30 True of false: Most of a cell’s ATP is produced in the cell’s mitochondria. true 30

31 True of false: Mitochondria contain DNA. true 31
