- 7. Cell theory proposed by early scientists that was disproven.
- 9. functions include synthesis of carbohydrates, lipids and steroid hormones.
- 16. a pigment that captures the energy of sunlight for photosynthesis.
- 19. means little organ.
- 20. used by bacteria to attach to a host cell.
- 21. an extra layer of protection of most bacteria.
- 22. garbage collector of the cell.
- 24. is a cell division for growth, repair, and maintenance.
- 26. structure of the cell that synthesizes ribosomes.
- 27. they appear to have role in in separating two chromosomes in cell division.
