Across
- 3. cellular organelles where cellular respiration occurs
- 7. net movement of the particles of a substance from where they are more concentrated to where they are less concentrated
- 8. straight hollow tube of proteins that gives rigidity, shape, and organization to a cell
- 12. having a lower concentration of solute than another
- 13. long, thin, whip-like structures with a core of micro-tubules, that enable some cells to move
- 14. membrane bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides
- 16. main energy source that cells use for for most of their work
- 17. small membrane bound sac that functions in moving products into, out of, and within a cell
- 18. short structures projecting from a cell and containing bundles of micro-tubules that move a cell through its surroundings or move fluid over the cells surface
Down
- 1. solid rod of protein, thinner than a micro-tubule, that enables a cell to move or change shape
- 2. cluster of proteins and nucleic acid that constructs proteins in a cell
- 4. having a higher concentration of solute than another solution
- 5. ball like mass of fibers and granules in a cell nucleus
- 6. the central core that contains protons and neutrons
- 8. photograph of the view through a microscope
- 9. organelle found in some plant cells and certain unicellular organisms where photosynthesis takes place
- 10. part of the cell with a specific function
- 11. having a solute concentration equal to that of another solution
- 15. passive transport of water across a selectively permeable membrane
- 17. membrane bound sac that buds from the endoplasmic reticulum or the Golgi apparatus
