Across
  1. 2. short, filamentous projections on a bacteria cell used for adhering to other bacteria cells
  2. 4. structures that give the cell its shape and help organize the cell's parts
  3. 6. the complete, infected form of a virus outside a host cell
  4. 9. life molecular structure of DNA - any behavior that yields construction of an identical copy of itself
  5. 13. the protein shell of a virus, encloses the genetic material of the virus
  6. 14. the transport system for molecules needed for certain changes and specific destinations - rough ER has ribosomes attached to it and smooth ER does not
  7. 16. a living cell in which a virus reproduces
  8. 17. a plastid that contains chlorophyll and in which photosynthesis takes place
  9. 20. the digestive system in a cell - breaks down molecules into their base components
  10. 21. the virus reproduces and then destroys the host cell and is released
  11. 23. usually visible as a dark spot in the nucleus, and is the location of ribosome formation
  12. 24. an organism with a nucleus and other membrane bound organelles
  13. 25. organelles organelles protected by a double or single membrane
  14. 27. where the DNA is kept and RNA is transcribed - control center
  15. 28. the smallest structural and functional unit of an organism
  16. 31. changes molecules and divides them into small membrane contained sacs called vesicles, which can be sent to various locations in the cell
  17. 32. Deoxyribonucleic acid-a molecule that carries the genetic instructions of organisms
  18. 33. the material between the plasma membrane (cell membrane) and the nuclear envelope - the fibrous proteins that occur in the cytoplasm (cytoskeleton) maintain the shape of the cell, anchor organelles, move the cell, and control internal movements of structures
  19. 34. similar to flagella in structure and function, but is shorter and moves differently - a cell usually has hundreds or thousands that move in unison
Down
  1. 1. a eukaryotic cell in which all the organelles are contained in membranes and doesn't have a cell wall
  2. 3. rod-shaped organelles that can be considered the power generators of the cell (powerhouse of the cell)
  3. 5. the theory that suggests that mitochondria and plastids in eukaryotic cells were once independent prokaryotic cells
  4. 7. when RNA is translated into protein through protein synthesis; float freely in the cytoplasm and are also bound to the endoplasmic reticulum
  5. 8. the formation of biological viruses during the infection process in the target host cells
  6. 10. an organism without a membrane bound nucleus or organelles
  7. 11. small storage bubbles found in animal cells
  8. 12. the phospholipid bilayer membrane which surrounds the genetic material and nucleus in eukaryotic cells
  9. 15. semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell - the most common molecule in it is phospholipids
  10. 18. a small, infectious agent that replicates only inside the living cells of other organisms (not considered living)
  11. 19. a viral reproduction cycle in which the viral DNA is added to the host cell's DNA and is copied along with the host cell's DNA
  12. 22. vacuole an organelle found in plant cells that is surrounded by a membrane and functions to hold materials and waste
  13. 26. proteins with a sugar attached to them
  14. 29. a eukaryotic cell with membrane bound organelles and a cell wall
  15. 30. a slender whip-like structure that allows single celled organisms to move
  16. 31. material the medium by which instructions are transmitted from one generation of organisms to the next
