Across
  1. 4. Ψ = Ψs + Ψp. Water moves high Ψ → low Ψ. Pure water Ψ = 0
  2. 5. Organelle; digest waste/old organelles
  3. 7. water molecules across a semipermeable membrane from a region of higher water concentration (low solute) to lower water concentration (high solute)
  4. 8. _______ mosaic model; phospholipid bilayer + cholesterol + integral/peripheral proteins
  5. 9. Organelle; Plants; turgor pressure
  6. 10. Organelle; photosynthesis (thylakoid + stroma)
  7. 12. no nucleus, circular DNA, 70S ribosomes, plasmids, cell wall
  8. 13. ________ diffusion; molecules move across a cell membrane from an area of higher concentration to lower concentration, assisted by specialized membrane proteins
  9. 16. _____ transport; endocytosis (phago/pino/receptor-mediated), exocytosis
  10. 18. Prokaryotic and Eukaryotic
  11. 19. Organelle; ER; protein synthesis + folding
  12. 20. net movement of molecules or ions from an area of higher concentration to an area of lower concentration
Down
  1. 1. theory stating that mitochondria and chloroplasts were free-living prokaryotes (evidence: own circular DNA, double membrane, 70S ribosomes, binary fission)
  2. 2. No ATP; diffusion, osmosis, facilitated diffusion
  3. 3. Organelle; ATP via cellular respiration (matrix + inner membrane/cristae)
  4. 6. Organelle; DNA storage, transcription
  5. 11. Requires ATP; pumps; Na+/K+-ATPase pumps 2Na+ out, 2K+ in per ATP
  6. 14. membrane-bound nucleus, linear chromosomes, organelles, 80S ribosomes
  7. 15. Organelle; ER; lipid synthesis, detox
  8. 17. Organelle; modify, sort, package and ship proteins
  9. 18. structure in plants, fungi, bacteria
