Presentation on theme: "AIM: Describe the different cell organelles and their functions."— Presentation transcript:

1 AIM: Describe the different cell organelles and their functions.
TOPIC: Cells AIM: Describe the different cell organelles and their functions. Do Now: Explain what all living cells are made up of. HW: Complete the Cell Theory Worksheet by reading text pgs

2

3 Cell Membrane

4 “SECURITY GUARD”

5 Plasma Membrane Surrounds the cell

6 Semi-permeable or Selectively permeable: controls what enters & leaves the cell

7 Made of a bilayer of lipids with proteins

8

9

10 Cytoplasm

11 Jellylike material Holds cell organelles

12

13 Nucleus

14 “BRAIN” of the cell (Control center of the cell)

15 Controls all cell activities
Stores hereditary information (DNA)

16 Nucleolus:produces ribosomes

17 Surrounded by the nuclear membrane

18 Nucleus of a Mouse Spleen Cell

19 Onion Cells

20 Cheek Cell

21 Ribosomes

22 Make proteins

23 Found Floating free in cytoplasm

24 on Endoplasmic Reticulum

25 Endoplasmic Reticulum (ER)
Nucleus

26 “HIGHWAY OF THE CELL”

27 Channels in the cytoplasm
Used to TRANSPORT materials

28 Rough ER: ribosomes on surface
Smooth ER: no ribosomes on surface

29 Rough ER

30 Smooth ER

31 Mitochondria

32

33 “POWERHOUSE” of the cell
Mighty Mitochondria

34 Site of cellular respiration
(Where ENERGY is made) ATP

35

36 TOPIC: Cells MI: What are the parts of a cell
TOPIC: Cells MI: What are the parts of a cell? Do Now: Take out Cell Theory Sheet HW: Read text pgs. 38 – 45, p. 45 #’s 1-4

37 Vacuoles

38 Plant cell

39 Stores materials (food, water, wastes…)

40 Animal = many small Plant = few large

41 Golgi Bodies

42

43 When a protein is made in the ER, something called a vesicle is made
When a protein is made in the ER, something called a vesicle is made. This vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed. After the Golgi does its work on the molecules inside the sac, a secretory vesicle is created and released into the cytoplasm. From there, the vesicle moves to the cell membrane and the molecules are released out of the cell.

44 “UPS / POST OFFICE” Collects, packages, and sends materials out of the cell

45 Lysosome

46

47 Contain digestive enzymes that:
1. digest food 2. break down old organelles & bacteria

48

49

50

51

52

53

54 Centriole

55 Used in cell division

56

57 Cell Wall

58 Outer wall of plant cell
Gives cell shape and support RIGID

59 CELL WALL Cell Membrane

60 Chloroplasts

61 Carry out photosynthesis
Contain green pigment called chlorophyll

62

66 Review: Which structure composed mainly of proteins and lipids, aids in maintaining homeostasis in the cell? (1.) chromosome (2.) nucleolus (3.) cell membrane (4.) cell wall

67 2. In which organelle would water and dissolved minerals be stored. (1
2. In which organelle would water and dissolved minerals be stored? (1.) vacuole (2.) lysosome (3.) nucleus (4.) ribosome

68 3. The rigidity (support) of a plant cell is due primarily to the presence of the (1.) DNA (2.) cell membrane (3.) cell wall (4.) lysosomes

69 4. The structure most closely associated with the destruction of worn out cell organelles is the (1.) lysosome (2.) vacuole (3.) golgi apparatus (4.) chromosome

70 5. Which structure is found ONLY in animal cells?
(1.) cell wall (2.) vacuoles (3.) centrioles (4.) ribosomes

71 6. The organelle most closely associated with the manufacture of proteins within the cell is the (1.) ribosome (2.) lysosome (3.) nucleolus (4.) cell membrane

72 7. Which structure chiefly functions in intracellular transport?
(1.) vacuole (2.) mitochondrion (3.) golgi apparatus (4.) endoplasmic reticulum

73 8. The cell wall is (1.) selectively permeable (2.) rigid (3.) living (4.) a hardened cell membrane

74 9. Cyanide, a metabolic poison, interferes with the production of energy. Which cell organelle does cyanide most directly influence first in this situation? (1.) nucleus (2.) lysosome (3.) mitochondria (4.) ribosomes

75 10. The structure that is known as the control center of the cell is the
(1.) vacuole (2.) cell membrane (3.) lysosome (4.) nucleus
