Across
  1. 2. in eukaryotic cells, all cellular contents outside the nucleus; in prokaryotic cells, all of the cells' contents
  2. 4. cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis
  3. 7. property of biological membranes that allows some substances to pass across it while others cannot; also called semipermeable membrane
  4. 12. fundamental concept of biology that states that all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produced from existing cells
  5. 13. specialized structure that performs important cellular functions within a cell
  6. 14. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
  7. 15. unicellular organism that lacks a nucleus
  8. 16. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
  9. 17. thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
  10. 18. cell organelle that stores materials such as water, salts, proteins, and carbohydrates
Down
  1. 1. cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
  2. 3. flexible double-layered sheet that makes ups the cell and forms a barrier between the cell and its surroundings
  3. 5. the center of an atom, which contains the protons and neutrons; in cells, the structure that contains the cell's genetic material in the form of DNA
  4. 6. basic unit of all forms of life
  5. 8. organism whose cells contain a nucleus
  6. 9. internal membrane system found in eukaryote cells; place where lipid components of the cell membrane are assembled
  7. 10. network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
  8. 11. organelle in cells that modifies, sorts, and packages proteins and other material from the endoplasmic reticulum for storage in the cell or release outside the cell
  9. 12. strong, supporting layer around the cell membrane in some cells
