Across
  1. 4. Tightly coiled, organized DNA
  2. 6. Organisms that make their own energy from alternative energy forms
  3. 7. Long whip-like structure that some cells use to propel themselves through their environment
  4. 11. Organisms that consume other organisms for energy
  5. 13. Cellular respiration without oxygen
  6. 14. small structures that assemble proteins
  7. 19. When a cell membrane allows some substances to pass through but not others
  8. 23. surrounds all cells and regulates what comes in and what goes out
  9. 24. When substances move across a semipermeable membrane without doing any work
  10. 26. structures that perform specific functions in a cell
  11. 28. Several types of long, thin fibers anchored to various parts of the cell. Helps the cell maintain and change its shape.
  12. 29. Modifies and packages proteins into vesicles
  13. 30. The process of breaking down molecules to produce ATP
Down
  1. 1. Makes most of the cell's ATP
  2. 2. small organelles that dispose of old cellular structures and destroy foreign substances
  3. 3. network of tubes that help produce and transport proteins, sometimes containing ribosomes
  4. 5. The free movement of molecules from an area of high concentration to low concentration
  5. 8. Contains information for making proteins and plays a role in regulating many cellular processes
  6. 9. When there is high concentration of a substance on one side of a cell membrane and low concentration on the other
  7. 10. groups of similar cells that work together
  8. 12. The free movement of water across a semipermeable membrane from an area of high concentration to low concentration
  9. 13. When a cell must do work to move substances across a semipermeable membrane
  10. 15. groups of tissues
  11. 16. A green pigment that absorbs sunlight in plants
  12. 17. When bacteria perform glycolysis they release lactic acid.
  13. 18. Small bubble-like structure that transports proteins to their final destination
  14. 20. The location the light dependent phase of photosynthesis takes place in.
  15. 21. organisms are made of cells, cells can divide to make new ones, and cells come from other cells
  16. 22. Most bacteria, algae, fungi, and plants have this rigid structure that protects the cell
  17. 25. The energy currency cells use to power their processes.
  18. 27. Organisms who get their energy from the sun do this
