1 The Cell The basic unit of all living things 1

2 Robert Hooke was the first to name the cell (1665) 2

3 The Cell Theory The cell is the unit of Structure of all living things. The cell is the unit of Function of all living things. All cells come from Pre-existing cells. 3

4 Two Major Cell Types Prokaryotic cells (Streptococcus, E.coli, etc.) NO NUCLEUS Eukaryotic cells. These include: plants, animals, fungi, protists HAVE A NUCLEUS 4

5 ANIMAL CELL 5

6 PLANT CELL 6

7 CELL MEMBRANE CELL MEMBRANE: All cells are covered by a cell membrane; it regulates what comes in and goes out of the cell. Also Called the PLASMA MEMBRANE Found in both plant and animal cells 7

8 Cell Membrane also called the Plasma Membrane 8

9 CYTOPLASM Cytoplasm jelly like substance that fills cells; made of mostly water; holds the organelles Found in plant and animal cells 9

10 NUCLEUS Nucleus contains the cell s DNA and is the control center of the cell Found in both plant and animal cells. 10

11 11 RIBOSOME Ribosome the site where amino acids are hooked together to make proteins This is the site of Protein Synthesis Found in both plant and animal cells

12 ENDOPLASMIC RETICULUM -found in both plants and animals System of Channels that transport proteins in a cell. Some reactions take place on the surface Two types Rough-with Ribosomes on them and Smooth- no ribosomes on them 12

13 GOLGI BODIES Responsible for labeling, sorting and packaging chemicals (proteins) and secreting (releasing) them from the cell 13

14 VACUOLES Vacuoles store water and other materials Found in both plant and animal cells Plants have very large vacuoles. Animals have small vacuoles 14

15 Food Vacuole 15

16 LYSOSOME Lysosomes digest food particles, wastes, cell parts and foreign invaders. They have such powerful enzymes they can destroy a whole cell. Example: Tadpole s tail. Found in animal cells 16

17 Mitochondria Makes Energy for Cell. Energy is also called ATP Site of Cellular Respiration It takes in oxygen and glucose and releases Carbon dioxide, water and ATP Found in both plant and animal cells. 17

18 Some Organelles are only found in Plant Cells Do you know which ones? 18

19 CELL WALL Cell Wall the cell wall gives structure and support to the cell membrane. Only found in plant cells 19

20 CHLOROPLASTS All plant cells contain Chloroplasts. They are the organelle responsible for _photosynthesis_ which uses the sun to make glucose(sugar). Chloroplasts are green due to a pigment called chlorophyll. Only found in plant cells 20

21 There is one organelle found only in Animal Cells. Can you name it?

22 The Centrioles These are necessary for Animal cell Division. Plants manage without them. 21

23 COMPARISON OF ORGANELLES TO ORGAN SYSTEMS ORGANELLE ORGAN ORGAN SYSTEM NUCLEUS BRAIN NERVOUS SYSTEM CELL MEMBRANE LUNGS RESPIRATOR Y SYSTEM LYSOSOME STOMACH DIGESTIVE SYSTEM CELL MEMBRANE KIDNEY EXCRETORY SYSTEM 23

24 LINKING HOW ORGANELLES WORK TOGETHER NUCLEUS CONTROLS THE RATE OF PROTEIN SYNTHESIS BY RIBOSOMES CELL MEMBRANE REGULATES THE PASSAGE OF OXYGEN INTO THE CELL TO BE USED BY MITOCHONDRIA AFTER A LYSOSOME DIGESTS OLD ORGANELLES THE CELL MEMBRANE RELEASES THEM OUT OF THE CELL THE GOLGI BODY PRODUCES LYSOSOMES WHICH ARE USED TO DIGEST BACTERIA 24

25 WRAP UP 1. HEREDITARY INFORMATION IS STORED INSIDE THE: A. RIBOSOMES B. NUCLEUS, C. MITOCHONDRIA 25

26 WRAP UP 2. DIAGRAM TO THE RIGHT REPRESENTS: A. A CHLOROPLAST CARRYING OUT RESPIRATION B. A LYSOSOME CARRYING OUT PHAGOCYTOSIS C. A MITOCHONDRIA CARRYING OUT RESPIRATION 26

27 WRAP UP 3. LEVELS OF ORGANIZATION FOR STRUCTURE AND FUNCTION IN THE HUMAN BODY FROM LEAST COMPLEX TO MOST COMPLEX ARE: A. CELLS-->TISSUES-->ORGANS-- >SYSTEMS B. SYSTEMS-->ORGANS-->TISSUES-- >CELLS C. CELLS-->ORGANS-->TISSUES-- >SYSTEMS 27

28 WRAP UP 4. STUDIES OF FAT CELLS AND THYROID CELLS SHOW THAT FAT CELLS HAVE FEWER MITOCHONDRIA THAN THYROID CELLS. A BIOLOGIST WOULD MOST LIKELY INFER THAT FAT TISSUE: A. HAS ENERGY REQIREMENTS EQUAL TO THOSE OF THYROID TISSUE B. REQUIRES LESS ENERGY THAN THYROID TISSUE C. REQUIRES MORE ENERGY THAN THYROID TISSUE 28
