35. 6. Produces ribosomes. 7. Has ribosomes on its surface. 8
6. Produces ribosomes. 7. Has ribosomes on its surface. 8. Holds all cell organelles. 9. Contains DNA. 10. Controls what enters and leaves the cell.

36. Mitochondria

38. “POWERHOUSE” of the cell
Mighty Mitochondria

39. Where ENERGY is produced (cell respiration)
ATP

41. Vacuoles

42. Stores materials (food, water, wastes…)

43. Animal = many small
Plant = few large

44. Golgi Bodies

46. 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.

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

48. Lysosome

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

56. Centrioles: used for cell division

59. CELL WALL
Cell Membrane

60. Cell Wall:
Outer wall of plant cell
Gives cell shape and support
RIGID

62. 2. Chloroplasts:
Carry out photosynthesis
Contain green pigment called chlorophyll
