3 A. CELL THEORY 1)All living things are made of one or more cells. 2)Cells are the basic unit of structure and function in living things. 3)Living cells come only from other living cells. 2

4 These cells have a nucleus. Nucleus is a membrane covered organelle that holds the DNA. Examples are plant and animal cells. B)Two Types of Cells: These cells DO NOT have a nucleus. DNA exists in loops that floats freely in the cell. An example is bacteria 3

5 Prokaryotic Cell Eukaryotic Cell 4

6 Large No Cell wall Small Vacuoles No Chloroplasts Cell wall Large Vacuoles Chloroplasts 5 C) COMPARING TWO EUKARYOTIC CELLS: ANIMAL CELL VS.PLANT CELL

7 1) ORGANELLES: tiny organs in the cell. 2) CYTOPLASM: fluid filling inside the cell membrane. makes up the majority of cell’s mass. D)SOME CELL TERMS & STRUCTURES: 6

8 Nucleolus 7 Golgi Body Endoplasmic Reticulum Vacuole Nucleus Mitochondrion Cell membrane Lysosome

9 3) CELL MEMBRANE controls movement of materials into and out of the cell holds cell together Cell membrane Animal Cell 8

10 Cell membrane Animal Cell Cell membrane made of special lipids called “phospholipids” 9

11 One phospholipid molecule. 10

12 A model of a section of phospholipid molecules that make up the cell membrane. 11

13 Cell membrane Animal Cell 12

14 found in animal cells. it is a protein “framework” inside the cell that gives the cells their shape. 4) CYTOSKELETON 13 found in plant cells not animal cells provides strength and support for plant cells. made of cellulose (long chains of sugar molecules) 5) CELL WALL

15 Cell wall Cell membrane Plant Cell 14

16 1) Nucleus: the control center of the cell stores DNA (a)nucleolus - dark spot inside the nucleus, which makes ribosomes. E)ORGANELLES OF CELLS: 15

17 (b)nuclear membrane - controls movement of materials in and out of nucleus. (c) DNA - stores information for making proteins 16

18 Nucleus DNA Nucleolus Animal Cell Nuclear membrane 17

19 2) RIBOSOME tiny grain like particles usually found along the E.R. proteins are made here Ribosome Proteins Amino acids 18

20 Close as you get to a real picture of a Ribosome. It is made of RNA and protein. 19

21 3) Endoplasmic Reticulum (ER): makes lipids the delivery system of the cell for compounds such as proteins through its tubular connections. 20

22 Endoplasmic reticulum Endoplasmic reticulum Ribosomes Animal Cell 21

23 4) Mitochondria: the “Power House” of the cell releases energy packets of ATP for use in the cell. Mitochondria Outer membrane Inner membrane 22

24 Mitochondria A real picture of a mitochondrion. Spelling of word ending is –ion for singular and –ia for plural 23

25 Mitochondria More mitochondria 24

26 5) Chloroplast: “Solar Panels” for capturing energy they use energy from sunlight to make food in plant cells (i.e. glucose). Outer membrane Inner membrane Chloroplast 25

27 Real picture of Chloroplasts 26

28 More pictures of real Chloroplasts The green round structures are chloroplasts 27

29 Cell membrane Mitochondria Chloroplast Vacuole Plant Cell 28

30 Vacuole 6) Vacuole: “Storage Tanks” of the cell store water, food and waste. Animal Cell Plant Cell 29

31 7) Golgi body: packages and transports materials out of the cell. Golgi complex Animal Cell 30

32 8) Lysosome: “Clean-up and Recycling Crew” digest food particles, wastes, cell parts, and foreign invaders. Lysosome Vesicle with food Animal Cell 31

33 More pictures of Lysosomes Lysosomes 32

34 Summary of organelles and their functions 33

35 Pictures of different cells. These are cells from inside the cheek of your mouth. 34

36 White Blood Cells Red Blood Cells 35

37 This is a Plant Cell found in many fish aquariums 36

38 A Neuron is a nerve cell that is part of our nervous system. 37

39 This shows different types of muscle cells which make up muscle fiber. Muscle Cells 38
