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