11 Biology - Cells
Across
- 3. Organisms that can produce their own food using energy from sunlight or other sources.
- 7. The gel-like substance that fills the cell and contains organelles.
- 8. The organelles responsible for protein synthesis.
- 9. Organelles that produce ATP, the energy currency of the cell, through cellular respiration.
- 10. The diffusion of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
- 12. ____ transport: The movement of substances across a membrane with the concentration gradient, without requiring energy.
- 15. _____ fission: A form of asexual reproduction in which a single cell divides into two identical cells.
- 16. Cell ____ The scientific theory that all living things are composed of cells, which are the basic structural and functional units of life.
- 17. A network of protein fibers that provides support and shape to cells.
- 18. The organelle that contains the genetic material of a eukaryotic cell.
- 19. A type of cell with a nucleus and membrane-bound organelles.
- 20. Cell ____ The semi-permeable membrane surrounding a cell that controls the exchange of materials between the cell and its environment.
- 21. Organisms that rely on other organisms for food.
Down
- 1. An organelle involved in protein and lipid synthesis, consisting of a network of membranes and tubes.
- 2. The movement of particles from an area of higher concentration to an area of lower concentration, driven by the concentration gradient.
- 4. Surface area-to-volume ___
- 5. Concentration _______ The difference in concentration of a substance between two regions, which can drive passive or active transport.
- 6. An organelle involved in modifying, sorting, and packaging proteins for transport.
- 11. Allowing only certain substances to pass through a membrane while excluding others.
- 13. A type of cell without a nucleus or membrane-bound organelles, typically smaller than eukaryotic cells.
- 14. An organelle involved in transport and storage of materials within the cell.
