Across
  1. 2. motor protein that can activate microtubules in flagella to move
  2. 3. 25 nm hollow tubes that determine cell motility and shape
  3. 6. can be cellulose, pectin, mannan, or silicon dioxide in algae
  4. 7. the space between the inner and outer membranes of mitochondria
  5. 9. membrane-bound sacs in which glycoproteins are made
  6. 11. surrounds the cell soma and flagella
  7. 16. 80S in eukaryotes (70S in prokaryotes)
  8. 17. DNA wound around histone proteins
  9. 20. ER that processes raw nutrients from food and synthesizes phospholipids
  10. 21. the substance of a fungal cell wall
  11. 24. a membrane sac that carries food into the cell
  12. 26. 7 nm strands of actin that assist with cell division and amoeboid motion
  13. 27. source of energy for eukaryotic and archaeal flagella movement
  14. 28. "powerhouse of the cell" - site of aerobic respiration
Down
  1. 1. "tiny stomach" of the cell, acid and enzymes digest food that is brought into the cell
  2. 4. DNA becoming RNA, attached to the nuclear envelope
  3. 5. outermost boundary made of polysaccharides (slime or capsule)
  4. 8. nucleosomes twisted into a condensed structure
  5. 10. "little nucleus" - organelle that makes rRNA
  6. 12. organelle that contains pigments like chlorophyll
  7. 13. "karya" - a double-membraned structure containing DNA
  8. 14. "endoplasmic ____" (ER) a processing organelle attached to the nucleus
  9. 15. complex that modifies proteins and packages them for transport out of the cell
  10. 18. like small flagella, can move liquid media outside the cell
  11. 19. dynamic protein filaments that transport substances and control cell shape
  12. 20. steroids that loosen/stabilize the phospholipid membrane)
  13. 22. grabs, pulls, and propels the cell forward in a serpentine pattern with whiplike action
  14. 23. intermediate fibers, 8-12 nm, which position organelles
  15. 25. folds in the inner membrane of a mitochondrion
