Across
  1. 4. - protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton
  2. 6. - cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
  3. 10. - flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings
  4. 12. - organism whose cells contain a nucleus
  5. 13. - fluid portion of the cell outside the nucleus
  6. 14. - specialized structure that performs important cellular functions within a eukaryotic cell
  7. 15. - network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
  8. 16. - strong, supporting layer around the cell membrane in some cells
Down
  1. 1. - thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
  2. 2. - tubular structured polymers which are found throughout the cytoplasm and forms a component of the cytoskeleton
  3. 3. - cell organelle that stores materials such as water, salts, proteins, and carbohydrates
  4. 5. - 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. 7. - property of cellular membranes that only allows certain molecules to enter or exit the cell.
  6. 8. - in cells, structure that contains the cell's genetic material in the form of DNA
  7. 9. - unicellular organism that lacks a nucleus
  8. 11. - bubble-like membranous structure that stores and transports cellular products, and digests metabolic wastes within the cell
  9. 16. - basic unit of all forms of life
