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