Identify Cell Organelles
12. _________________________ #1: organelle that receives proteins and other newly formed materials from the ER, packages them and distributes them to other parts of the cell or to the outside of the cell
13. _________________________ #2: organelle(s) that store water, food and other materials; sometimes store waste products
14. _________________________ #3: organelle(s) that convert energy stored in food to energy the cell can use to live and function; does cellular respiration - breaking down sugar to make
15. _________________________ #4: organelle(s) that capture energy from sunlight and change it to a form of energy cells can use in making food
16. _________________________ #5: large organelle that produces & stores the cell’s DNA (genetic material)and other important information
17. _________________________ #6: thick, clear gel-like fluid inside the cell that cushions organelles and allows organelles to move around as needed
18. _________________________ #7: a protective barrier that encloses, protects and supports a cell; controls what enters and leaves the cell
19. _________________________ #8: organelle(s) that make protein
20. _________________________ #9: an organelle with a network of membranes that produces many substances: folded membranes that help produce proteins, lipids & other materials – then sends them to where they are needed
cell B
21. ________________________ #10: rigid outer structure that surrounds, protects and supports a cell
22. _______________________ #11: contain substances that break down large food particles into smaller ones also break down old cell parts
23. Cell A is a __________________________ cell
24. Cell B is a _________________________ cell
25. Name 2 organelles that a plant cell has that an animal cell does not have.
