37. Vacuoles

38. Plant cell

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

40. Animal = many small
Plant = few large

41. Golgi Bodies

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

1. digest food
2. break down old organelles & bacteria
