Across
  1. 7. Specialized, membrane--bound structures within a cell that perform specific, vital functions
  2. 8. A specialized protein embedded in cell membranes that moves ions, small molecules, and macromolecules
  3. 9. movement of molecules or ions across a cell membrane
  4. 12. A solution with the same solute concentration (an water potential) as another solution, usually inside a cell
  5. 13. The membrane-bound organelle in eukaryotic cells that acts as the cell's control center
  6. 15. microscopy to observe shape, organelles
  7. 16. An organism made of a single cell that performs all life functions independently
  8. 18. The ability of a living system to maintain a stable, constant internal environment
  9. 23. Double layer of lipids that forms the core structure of all cell membranes, creating a barrier where water-loving heads outward
  10. 25. Long, whip-like appendages that extend from the surface of cells
  11. 26. A vital celluar machine, made of ribosomal RNA and proteins
  12. 27. The movement of substances across a cell membrane down their concentration gradient without the cell using any energy
  13. 29. The minimum pressure needed to stop water from moving across a semipermeable membrane
  14. 31. The amount of a substance dissolved in a specific amount of liquid
  15. 32. Describes the cell membrane as a flexible, dynamic barrier made of a phospholipid bilayer
  16. 35. A solution with a higher solute (like salt or sugar) concentration compared to another solution
  17. 36. Cell organelle that acts as the "post office," modiying, sorting
  18. 37. A crucial semipermeable barrier enclosing all cells, separating their internal contents from the external environment
Down
  1. 1. The fundamental structure of cell membranes, consisting of two ayers of phospholipids with their water-loving phosphate
  2. 2. A solution with a lower solute concentration compared to another solution
  3. 3. Jelly-like substance filling a cell, enclosed by the cell membrane
  4. 4. A key organelle in eukaryotic cells that acts as the cell's processing
  5. 5. A single-celled organism whose cells lack a mebrane-bound nucleus and other organells
  6. 6. A membrane-bound organelle within a cell,acting as a versatile storage sac for water, nutrients, waste, and other molecules
  7. 10. Essential organelles in eukaryotic cells, known as the "powerhouses"
  8. 11. A vast network of membranes in eukaryotic cells
  9. 14. Small, green, oval-shaped organelles in plant/algae cells
  10. 17. Describes molecules or substances that are attracted to and can mix with water
  11. 19. a mixture of a weak acid and its salt
  12. 20. Molecules that repel water, don't mix with it easily and are "water-fearing"
  13. 21. A small, circular, double-standard DNA molecule that exists separately from a cell's main chromosomal DNA
  14. 22. Unique size, shape, and banding patterns
  15. 24. Any organism whose cells have membrane-bound nucleus that houses its DNA
  16. 28. Fixed, often rectangular shape
  17. 30. The passive movement of water molecules across a selectively permeable membrane
  18. 33. Organisms made of multiple, interconnected cells that work together, allowing for complex structures
  19. 34. The natural, passive movement of molecules form an area where they are highly concentrated
