Across
- 2. in a molecule, uneven distribution of electrons
- 5. cell organelle that stores materials such as water, salts, proteins,and carbohydrates
- 8. a process by which liquid droplets are ingested by living cells; it is another type of endocytosis
- 9. fluid portion of the cell outside the nucleus
- 10. tendency of water to rise in a thin tube
- 13. process by which solids are ingested by living cells; it is another type of endocytosis
- 14. process of diffusion in which molecules pass across the membrane through cell membrane channels
- 15. cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can used by the rest of the cell
- 16. weak attraction between a hydrogen atom and another atom
- 17. network of protein filaments in a eukaryote cell that gives the cell its shape and internal organization and is involved in movement
- 19. unicellular organism that lacks a nucleus
- 22. tiny sacs that transport material within or outside the cell
- 23. when comparing two solutions, the solution with the greater concentration of solutes
- 25. property of biological membranes that allows some substances to pass across it while others cannot also called semi permeable substance
- 27. the process by which cells move materials from within the cell into the extracellular fluid
- 28. thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
- 29. fundamental concept of biology that states that all living things are composed of cells: that cells are the basic units of structure and function in living things, and that new cells are produced from existing cells
Down
- 1. microscope that uses multiple lenses and light to enlarge the image of a sample
- 3. the process by which cells move materials out of the cell
- 4. strong, supporting layer around the cell membrane in some cells
- 6. when the concentration of two solutions is the same
- 7. when comparing two solutions, the solution with the lesser concentration of solutes
- 9. attraction between molecules of the same substance
- 11. force of attraction Between different kinds of molecules
- 12. cellular transport where substances move against a concentration gradient
- 18. process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
- 20. diffusion of water through a selectively permeable membrane
- 21. a microscope with high magnification that uses electron beams in place of light
- 24. the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius
- 26. organism whose cells contain a nucleus
