Across
  1. 1. an organelle within the cells of plants and certain algae
  2. 3. a continuous membrane system that forms a series flattened sacs within the cytoplasm of eukaryotic cells
  3. 8. a solution that contains fewer dissolved particles than is found in normal cells and blood
  4. 9. any of the single-celled or multicellular organisms whose cells contains a distinct, membrane-bound nucleus
  5. 10. to the measure of the amount of a subcomponent in a solution
  6. 12. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport
  7. 14. the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed
  8. 15. the net passive movement of molecules or particles from regions of higher to regions of lower concentration
  9. 16. a structural layer next to the cell membrane with the primary role of giving the cell rigidity and protection from mechanical stress
  10. 18. a solution that contains more dissolved particles than is found in normal cells and blood
  11. 19. organic substances that maintain a constant pH over a given range by neutralizing the effects of hydrogen ions
  12. 21. a thick solution that fills each cell and is enclosed by the cell membrane
Down
  1. 1. a structure found inside the nucleus of a cell; made up of proteins and DNA organized into genes
  2. 2. a slender threadlike structure, especially a microscopic appendage that enables many protozoa, bacteria, spermatozoa, etc. to swim
  3. 4. the process of moving molecules across a cellular membrane through the use of cellular energy
  4. 5. the ability or tendency of the body or a cell to seek and maintain a condition of equilibrium
  5. 6. something having a strong affinity for water
  6. 7. compounds do not easily dissolve in water
  7. 11. a cell organelle that helps process and package proteins and lipid molecules
  8. 13. a solution that has the same salt concentration as cells and blood
  9. 17. a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell
  10. 20. the cell membrane as a tapestry of several types of molecules that are constantly moving
