CELL TOUR 2

4. / American biologist that provided evidence that mitochondria and chloroplasts within cells were at one time free living cells themselves
6. / only in animal cells; Help pull chromosome pairs apart to opposite ends of the cell
10. / a supporting structure that is formed by microtubules and microfilaments
11. / (initials) lacks ribosomes on its surface; makes membrane lipids, destroys toxic substances
12. / a motor protein that drives the bending movements of a cilium or flagellum
13. / a double twisted subunit that is part of the microfilaments in a cell
14. / organelle that makes proteins
16. / are the major component of the cell membrane
19. / semifluid substance inside a cell
20. / channels that perforate plant cell walls
23. / carry genes
24. / regulate the entry and exit of molecules from the nucleus
28. / set of “poker-chip-type’ of structure that forms the granum in choroplasts
29. / the solar power packs- trap light and convert it into chemical energy
31. / a junction that provides cytoplasmic channels between adjacent cells
32. / inner folding of the mitochondrion
33. / helps cell into a rowing motion parallel to the plasma membrane

1. / contains most of the cell’s genes in eukaryotic cells
2. / initials of a structure made out of glycoproteins such as collagen, proteoglycans and fibronectin in the cell
3. / specialized metabolic compartments that produce hydrogen peroxide and convert it to water
5. / inside the nucleus; disappears when cell divides
7. / thick fluid within chloroplasts
8. / this region contains the DNA in prokaryotic cells
9. / an apparatus that modifies, sorts and packages proteins
10. / Contains enzymes & pigments for Photosynthesis; Never in animal cells
12. / an anchoring function that fastens cells together into strong sheets
15. / responsible of cell respiration (transforms sugars to ATP), has its own DNA
17. / Bacteria and Archaea have this type of cell
18. / sacs that bud from the ER, Golgi or plasma membrane; in plants, stores organic nutrients, absorbs water and have pigments that attract pollinators
21. / a sac of digestive enzymes; in animal cells only
22. / plants, animals, fungi and protists have this type of cell
23. / the region between the plasma membrane and nucleus
25. / (initials) has ribosomes attached to it; produces new membranes.
26. / provide a force perpendicular to the plasma membrane to move the cell
27. / inner space of the mitochondrion
30. / a protein that in addition to actin is part of the microfilaments
