Across
  1. 7. microscopic hair-like structures involved in the movement of a cell
  2. 9. found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized to make up genes.
  3. 11. primary function is to produce and assemble the cell's ribosomes.
  4. 12. A state of balance among all the body systems needed for the body to survive and function correctly.
  5. 15. when molecules move across a cell membrane from a lower concentration to a higher concentration.
  6. 16. break down excess or worn-out cell parts.
  7. 17. the movement of molecules from a high concentration to a lower concentration through a smart barrier
  8. 18. the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
  9. 21. a structure that helps cells maintain their shape and internal organization
  10. 22. move substances into or out of the cell.
Down
  1. 1. a solution that has lower osmotic pressure
  2. 2. the site of protein synthesis in the cell.
  3. 3. play a critical role in the generation of metabolic energy in eukaryotic cells.
  4. 4. organic substances that maintain a constant pH over a given range by neutralizing the effects of hydrogen ions.
  5. 5. acts as the packaging center of the cell.
  6. 6. involved in lipid biosynthesis.
  7. 8. contains dna as well as being the control center of te cell
  8. 10. convert light energy into relatively stable chemical energy via photosynthesis.
  9. 13. provides protection for a cell.
  10. 14. contains the instructions needed for an organism to develop, survive and reproduce.
  11. 19. a biological membrane consisting of two layers of lipid molecules.
  12. 20. organizing microtubules that serve as the cell's skeletal system.
  13. 21. the wall of a cell in plants, bacteria, fungi, algae, and some archaea.
