Cells and Organelles

2. is studded with ribosomes that are responsible for making proteins.
5. are internal structures within a cell that perform specific functions.
7. are responsible for breaking down lipids.
8. the jelly-like material that the organelles sit in.
10. are some of the smallest cells and are never visible without a microscope.
14. are large organelles that break down glucose into ATP for energy.
16. is the basic unit of structure and function and the smallest unit that can carry on all living processes.
18. are embedded throughout the entire cell membrane.
19. are less complex and lack a nucleus.
20. the command center of the cell.
21. are responsible for breaking down proteins.
22. are only found in plant and fungal cells.

1. Cell membranes are composed of
3. long strands of DNA within the nucleus
4. a complex network of filaments and tubules that helps the cell keep its shape.
6. protects the cell and separates its cytoplasm from the environment.
9. created an improved microscope capable of 50 X magnification.
11. states that all living things are made of cells.
12. made of only one cell.
13. apparatus receives proteins from the ER and modifies them for transport to the cell membrane.
15. contain pores that allow certain substances, such as ions, to pass through the membrane.
17. lacks ribosomes and is responsible for making lipids.
