Across
- 4. carry genes
- 7. regulate the entry and exit of molecules from the nucleus
- 8. a junction that provides cytoplasmic channels between adjacent cells
- 9. organelle that makes proteins
- 10. responsible of cell respiration (transforms sugars to ATP), has its own DNA
- 11. this region contains the DNA in prokaryotic cells
- 12. are the major component of the cell membrane
- 13. a protein that in addition to actin is part of the microfilaments
- 14. a supporting structure that is formed by microtubules and microfilaments
- 17. only in animal cells; Help pull chromosome pairs apart to opposite ends of the cell
- 19. the solar power packs- trap light and convert it into chemical energy
- 21. the region between the plasma membrane and nucleus
- 24. inner space of the mitochondrion
- 25. Bacteria and Archaea have this type of cell
- 27. provide a force perpendicular to the plasma membrane to move the cell
- 30. (initials) lacks ribosomes on its surface; makes membrane lipids, destroys toxic substances
- 31. plants, animals, fungi and protists have this type of cell
- 32. (initials) has ribosomes attached to it; produces new membranes.
Down
- 1. sacs that bud from the ER, Golgi or plasma membrane; in plants, stores organic nutrients, absorbs water and have pigments that attract pollinators
- 2. thick fluid within chloroplasts
- 3. an apparatus that modifies, sorts and packages proteins
- 4. Contains enzymes & pigments for Photosynthesis; Never in animal cells
- 5. an anchoring function that fastens cells together into strong sheets
- 6. initials of a structure made out of glycoproteins such as collagen, proteoglycans and fibronectin in the cell
- 11. contains most of the cell’s genes in eukaryotic cells
- 12. channels that perforate plant cell walls
- 15. set of “poker-chip-type’ of structure that forms the granum in choroplasts
- 16. inside the nucleus; disappears when cell divides
- 18. a motor protein that drives the bending movements of a cilium or flagellum
- 20. semifluid substance inside a cell
- 22. a sac of digestive enzymes; in animal cells only
- 23. American biologist that provided evidence that mitochondria and chloroplasts within cells were at one time free living cells themselves
- 25. specialized metabolic compartments that produce hydrogen peroxide and convert it to water
- 26. helps cell into a rowing motion parallel to the plasma membrane
- 28. a double twisted subunit that is part of the microfilaments in a cell
- 29. inner folding of the mitochondrion
