Module 3 Cell Structure

3. The barrier around cells that protects them from the outside.
5. A solution whose concentration of solute is lower than inside the cell.
7. The process of making molecules by using absorbed molecules.
12. Water fearing
13. Organelles that make proteins.
15. Cells that don't have a nucleus nor any membrane-bound organelles.
16. ER that has many ribosomes attached to it.
17. A solution whose concentration has a higher concentration of solute than inside the cell.
20. The state of being equal or even.
21. cells that contain a nucleus and membrane-bound organelles.
22. A type of plastid that performs photosynthesis.
23. The movement of molecules from an area of higher concentration to an area of lower concentration.

1. The property of a membrane to only allow certain substances to pass across it.
2. A mode of transport that does not require the cell to use any energy.
3. A complex network of proteins that strengthen the cell and keep it from rupturing.
4. A cell organelle which manufactures the cells energy molecule, ATP.
6. Microtubules that help pull the DNA apart during cell division.
8. A storage "sack" in the cytoplasm that holds food or wastes.
9. vesicles that contain enzymes to break stuff down, animal cells only
10. Water loving
11. structure in the nucleus which assembles ribosomes
14. Units inside all cells which perform certain functions/tasks.
18. stores the DNA.
19. A solution whose concentration of solute is the same as inside the cell.
22. The study of cells.
