Across
  1. 5. any cell or organism that possesses a clearly defined nucleus.
  2. 9. the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
  3. 11. the membrane-enclosed organelle within a cell that contains the chromosomes
  4. 12. visicles move substances in cell.
  5. 14. a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism.
  6. 18. a thin polar membrane made of two layers of lipid molecules.
  7. 20. A substance that is dissolved in a solution.
  8. 23. is a kind of cellular transport where substances move against a concentration gradient.This means that the direction is from an area of lower concentration to an area of higher concentration.
  9. 25. an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.
  10. 26. visicles move substances out.
  11. 28. a type of cell that does not have a true nucleus or membrane-bound organelles.
  12. 29. its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others.
  13. 31. an organelle within the cells of plants and certain algae that is the site of photosynthesis.
  14. 32. water in/out
  15. 33. the source of energy for use and storage at the cellular level.
Down
  1. 1. :the membrane found in all cells that separates the interior of the cell from the outside environment.
  2. 2. the passive movement of molecules along the concentration gradient.
  3. 3. membrane-bound cell organelles that produce energy (ATP)
  4. 4. paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.
  5. 6. the normal process by which a less specialized cell undergoes maturation to become more distinct in form and function.
  6. 7. the net passive movement of molecules or particles from regions of higher to regions of lower concentration.
  7. 8. water in cell swells
  8. 10. separates the interior of the cell from the outside environment.
  9. 13. the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
  10. 15. is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations.
  11. 16. surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
  12. 17. a substance that dissolves a solute, resulting in a solution.
  13. 19. an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.
  14. 21. a membrane-bound cell organelle that is small in animal cell but is big in plant cell
  15. 22. water out cell shrinks
  16. 24. an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell.
  17. 27. specialized structures that perform various jobs inside cells.
  18. 30. membrane-bound cell organelle that contains digestive enzymes .They may be used to destroy invading viruses and bacteria.
  19. 31. the gelatinous liquid that fills the inside of a cell.
