Across
- 3. nucleated cells; have more complex organelles and allow for greater levels of organization and specialization
- 6. having a tendency to mix with or dissolved in water
- 9. Small membrane-bound sac that functions in moving products into, out of, and within a cell.
- 15. Deoxyribonucleis Acid; all organisms have it; inherited from parents and passed on to offspring; contains the coded instructions to make proteins.
- 17. organelle that makes protein; found in prokaryotes and eukaryotes; found free-floating in cytoplasm or on the rough-endoplasmic reticulum
- 19. A long, whip-like filament that helps in cell motility.
- 21. a two-layered arrangement of phosphate and lipid molecules that form a cell membrane
- 22. Process of diffusion in which molecules pass across the membrane through cell membrane channels
- 24. Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
- 27. Theory all living things are composed of cell(s); all cells come from other cells; and the cell is the basic unit of life
- 29. A network of long protein strands in the cytosol (cytoplasm) that helps support the cell
- 31. Endoplasmic Reticulum Synthesizes lipids for use in the cell membrane and other parts of the cell; lacks ribosomes
- 32. Theory explanation of the origins of eukaryotic cells; explains that prokaryotic cells entered other prokaryotes and now live together; evidence includes 1) mitochondria and chloroplasts have their own DNA, ribosomes, and phospholipid bilayers; and 2) mitochondria and chloroplasts are the size of modern day prokaryotes
- 33. A plastid containing chlorophyll, the site of photosynthesis
- 34. Structure that organizes motion of chromosomes; aids in cell division
- 35. eukaryotic; definitely lack cell walls; heterotrophic (consumer), multicellular
- 36. one of the DNA containing organelles in eukaryotic cells (this is not chloroplast or mitochondria)
- 37. the movement of substances across a cell membrane without the use of energy by the cell
- 39. Release of substances out a cell by the fusion of a vesicle with the membrane
- 40. Embedded in the bilayer of the cell membrane; allows the passage of ion up or down the concentration gradient
Down
- 1. eukaryotic, have cell walls, large central vacuoles, and chloroplasts in some leaf cells; autotrophic (producer), multicellular
- 2. protein that forms a channel to allow a particular molecule or ion to cross the plasma membrane
- 4. The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids
- 5. body a eukaryotic organelle that modifies proteins after translation.
- 7. Net movement of dissolved particles from higher concentration to a region of lower concentration
- 8. An organelle containing digestive enzymes, which will catalyze hydrolysis reactions
- 10. proteins that require energy to do work;
- 11. organelle that is the site of MOST of the ATP (energy) production; site of aerobic cellular respiration.
- 12. Microscope tool used to see very small organisms; uses light as its medium; magnifies using two lenses
- 13. tending to repel or fail to mix with water.
- 14. non-nucleated cells; have free-floating DNA, ribosomes, cytoplasm, cell membrane, cell wall, and sometimes flagella
- 16. These are attached to either the interior or exterior surface of the cell membrane
- 18. Wall A rigid structure that surrounds the cell membrane and provides support to the cell; made of cellulose in plants; made of chitin in fungi; not found in animal cells
- 20. fluid portion of the cell outside the nucleus
- 23. Membrane the semipermeable membrane surrounding the cytoplasm of a cell.
- 25. Endoplasmic Reticulum An endomembrane system covered with ribosomes where many proteins for transport are assembled; found only in eukaryotic cells
- 26. Movement of particles from low to high concentration across the membrane that requires energy (ATP).
- 28. process by which a cell takes material into the cell by infolding of the cell membrane
- 30. cell membrane protein that uses energy provided by ATP;
- 38. things (proteins) from a low concentration to a high
