Science

3. The net movement of water out of or into a cell
5. The portion of the cell outside the nucleus
11. Breaks down lipids, carbohydrates, and proteins
12. Converts chemical energy stored in food molecules into compounds for the cell
16. Where lipids are synthesized
17. Water channel protein
18. Modifies, sorts, and packages proteins and other materials
19. The driving force behind the movement of many substances across the cell membrane
21. Gives cell membranes a flexible structure
22. Helps maintain the cell’s shape and is involved in movement

1. Some substances can pass across them and others cannot
2. More Solute
4. Small particles of RNA and protein found throughout cytoplasm
6. The “organs” of the cell
7. Captures energy from the sun and converts it into chemical energy for a plant cell
8. Less Solute
9. Same solute
10. When molecules that cannot directly diffuse across the membrane pass through special protein channels
13. Strong supporting layer around the membrane
14. The diffusion of water through a selectively permeable membrane
15. A state of relatively constant internal physical and chemical conditions
20. Stores materials like water, salts, proteins and carbohydrates
