Cells

3. cell's digestive system
7. type of solution:"having lesser strength"
9. a small,membrane-bound sac that transports or stores material within cells
14. Australian pathologist that concluded all cells must come only from pre-existing cells
15. membrane bound vesicles of flattened sacs and stacks parallel to each other
16. most active region of the cell
18. a series of interconnected membrane-enclosed tubes and channels in the cytoplasm
19. particles are transported in large amounts or in bulk "out of the cell"
20. movement of solute molecules from an area of higher concentration to an area of a lower concentration of that solute in solution
21. British scientist who observed mass of tiny cavities from thin slices of cork
22. powerhouse of the cell
23. physiologically active,permanent sub-cellular structures performing metabolic functions
25. are small,membrane bound vesicles containing enzymes that break down fatty acids and hydrogen peroxide
26. movement of solvent across semi-permeable membrane from an area of high water concentration to an area of low concentration
27. ideal shape of an isolated cell
28. gatekeeper of the cell
29. uses cellular energy to move molecules across the plasma membrane, often uphill against a concentration gradient
30. type of solution:"having greater strength"

1. "cell-eating"
2. smallest cell,a bacterium
4. trigger cellular responses when specific molecules in the extracellular fluid bind them
5. regulate the movement of hydrophilic molecules through the plasma membrane
6. type of solution:"having the same strength"
8. "cell-drinking"
10. what the observations and conclusions of Schleiden,Schwann and Virchow established the cell theory
11. serve as identification tags and cell-surface attachment sites
12. site of protein synthesis in the cell
13. basic structural living unit of all organisms
17. control center of the cell
24. particles are transported in large amounts or in bulk "into the cell"
