  3. 6. an organelle found in plant and algae cells where photosynthesis occurs.
  4. 7. cells without a defined nucleus; usually smaller than eukaryotic cells
  5. 10. where genetic material is stored and controls the cell’s growth and reproduction
  6. 11. the arrangement of parts in an organism
  7. 13. the smallest functional and structural unit of all living things
  8. 14. material – deoxyribonucleic acid, a molecules that is present in all living cells and that contains information that determines traits.

  6. 9. the special, normal or proper activity of an organ or part.
  7. 12. membrane protective, flexible barrier that controls what goes in and out of the cell.
  8. 15. wall rigid structure that surrounds the cell membrane in plant cells; provide structure and support.
