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