  1. 2. Small units that are linked together chemically to form large protein molecules
  2. 4. The process by which molecules move from an area of higher concentration to an area of lower concentration
  3. 5. Any substance that cannot be broken down into simpler substances
  4. 6. Energy-rich organic compound (fat, oil, wax) that's made of carbon, hydrogen, and oxygen.
  5. 7. Organelles made of protein and RNA that direct protein synthesis in the cytoplasm
  6. 9. Rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions
  7. 10. A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food
  8. 11. A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
  9. 17. Device that produces magnified images of structures that are too small to see with the unaided eye
  10. 20. The movement of materials through a cell membrane using cellular energy
  11. 22. Specialized proteins that speed up chemical reactions
  12. 23. Ribonucleic acid; a nucleic acid that plays an important role in the production of proteins
  13. 26. The diffusion of water through a selectively permeable membrane
  14. 27. Control center of the cell
  15. 28. Compound made up of carbon, hydrogen, and oxygen atoms; major source of energy for the human body
Down
  1. 1. The movement of materials through a cell membrane without using energy
  2. 3. A jellylike fluid inside the cell in which the organelles are suspended.
  3. 8. Thin, flexible barrier around a cell; regulates what enters and leaves the cell
  4. 12. Deoxyribonucleic acid; the genetic material that carries information about an organism and is passed from parent to offspring.
  5. 13. A property of cell membranes that allows some substances to pass through, while others cannot
  6. 14. Basic unit of structure and function in living things
  7. 15. Cell organelle filled with enzymes needed to break down certain materials in the cell
  8. 16. A tiny cell structure that carries out a specific function within the cell.
  9. 18. Large organic molecule made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur
  10. 19. Organelles that package cellular material and transport them within the cell or out of the cell
  11. 21. Idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
  12. 24. Two or more elements that are chemically combined
  13. 25. Storage structures for food, water, minerals, waste
