Across
  1. 5. Occurs when a substance involved in acellular process causes the process to speed up.
  2. 8. Extension of the cytoskeleton; usually only one or a few on a cell; propels the cell through its environment using a protein motor
  3. 9. This is the internal balance of a system that keeps conditions stable
  4. 11. Found in bacteria outside the cell membrane and cell wall; protects the cell
  5. 12. An organism whose organs found mostly in plants
  6. 14. “Powerhouse” of the cell; transforms energy from sugars into usable energy for the cell; has an inner membrane that contains folds (cristae), allowing for more surface area to increase energy output and more proteins to be embedded in the membrane
  7. 15. When cells are in a solution that is less concentrated than their cytoplasm
  8. 17. Found mostly in plants;stores water, salts, sugars, and proteins
  9. 23. Lipids have a hydrophilic (water-loving) end and a hydrophobic (water-fearing) end, so they arrange themselves into two layers
  10. 24. The genetic material of the nucleus; contains DNA, RNA, and proteins
  11. 27. “Post office” of the cell; receives substances from the ER and packages them into membrane sacs called vesicles
  12. 28. A type of colorless plastid; found in plants and algae; stores starches, lipids, and proteins
  13. 29. Found in prokaryotes; contains the genetic material for the cell
  14. 30. A system of fibers in the cytosol that helps maintain the cell’s shape and provides protein motors
  15. 31. This is a group of organs that work together
  16. 32. Found inside chloroplasts; made of stacks of thylakoids,which contain the green pigment
  17. 34. The movement of molecules across a membrane using chemical energy.
  18. 37. A solution that is concentrated than the cytoplasm of a cell
  19. 39. Surrounds each cell of both prokaryotes and eukaryotes;protects the cell and allows certain materials to move through it
  20. 40. A type of pigmented plastid; found in plants and algae; converts light energy from the sun into chemical energy
  21. 41. A type of vacuole; found in human, animal, and animal-like cells (protozoans); contains digestive enzymes that digest food, kill bacteria and viruses, and recycle old cell parts
  22. 42. The diffusion of a solvent through a semipermeable membrane, a membrane that allows certain substances to pass through it but not others
Down
  1. 1. The parts inside a cell.
  2. 2. Consists of everything within the cell membrane except the nucleus
  3. 3. Transports compounds around the cell and helps maintain the cell’s shape;processes fats and breaks down toxic substances in liver cells
  4. 4. This theory states that Cells are the structural and functional units of all living things and Cells come only from other preexisting cells.
  5. 6. An organism with cells that contain membrane-surrounded organelles
  6. 7. Found in both prokaryotes and eukaryotes because it’s not surrounded by a membrane; contains proteins and RNA;
  7. 10. This is made of two or more cells that depend on each other to function
  8. 13. Found in plants, fungi, algae,and bacteria; provides strength and rigidity to the cell
  9. 16. The movement of molecules across a membrane without the use of chemical energy.
  10. 18. Transports compounds around the cell and helps maintain the cell’s shape
  11. 19. Contains RNA and proteins; area of the nucleus where ribosomes are assembled
  12. 20. water, salts, sugars, and proteins;nelles lack surrounding membranes
  13. 21. In multicellular organisms, cells are organized into this.
  14. 22. This is an organism that is made of only one cell.
  15. 24. Extension of the cytoskeleton; often cover an entire cell or a portion of a cell; shorter than flagella; propel the cell through its environment
  16. 25. Occurs when a substance produced by a cellular process causes the process to slow down or stop.
  17. 26. Molecules move through the cell membrane with the help of transport proteins.
  18. 33. The water pressure inside the central vacuole that keeps the cell rigid
  19. 35. This is In multicellular organisms, cells are organized into
  20. 36. Some unicellular organisms work together in this way.
  21. 38. When cells and the solution that they are in have the same concentration of solutes
