Across
- 8. (initials) lacks ribosomes on its surface; makes membrane lipids, destroys toxic substances
- 9. are the major component of the cell membrane
- 10. helps cell into a rowing motion parallel to the plasma membrane
- 11. /carry genes
- 14. a sac of digestive enzymes; in animal cells only
- 15. (initials) has ribosomes attached to it; produces new membranes.
- 16. the region between the plasma membrane and nucleus
- 18. only in animal cells; Help pull chromosome pairs apart to opposite ends of the cell
- 20. an apparatus that modifies, sorts and packages proteins
- 21. American biologist that provided evidence that mitochondria and chloroplasts within cells were at one time free living cells themselves
Down
- 1. Bacteria and Archaea have this type of cell
- 2. contains most of the cell’s genes in eukaryotic cells
- 3. /inside the nucleus; disappears when cell divides
- 4. a supporting structure that is formed by microtubules and microfilaments
- 5. specialized metabolic compartments that produce hydrogen peroxide and convert it to water
- 6. semifluid substance inside a cell
- 7. responsible of cell respiration (transforms sugars to ATP), has its own DNA
- 12. plants, animals, fungi and protists have this type of cell
- 13. organelle that makes proteins
- 17. provide a force perpendicular to the plasma membrane to move the cell
- 19. this region contains the DNA in prokaryotic cells
