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