Across
- 4. Found in plant cells. Contain chlorophyll that absorbs light for photosynthesis.
- 5. Vesicles that contain substances that digest excess or worn-out organelles and food particles.
- 10. Diffusion, Passive transport of ions and small molecules across the plasma membrane by transport proteins.
- 13. A tiny cell structure that carries out a specific function within the cell.
- 14. A fluid-filled cavity in a cell that is used for storage and support.
- 16. External solution that has a low solute concentration and high water concentration compared to body fluids.
- 18. External solution that has a high solute concentration and low water concentration compared to body fluids.
- 19. Wall, A protective layer, found outside the cell membrane of plant, fungal and bacterial cells, that helps to support the cell.
- 21. Where aerobic respiration takes place.
- 22. Cells without a nucleus or membrane bound organelles.
- 23. External solution that has the same solute concentration and water concentration compared to body fluids.
- 24. Reticulum, Membrane system of folded sacs and interconnected channels that serves as the site for protein and lipid synthesis.
Down
- 1. Small structures found in the cytoplasm of living cells where protein synthesis takes place.
- 2. the basic structural and functional unit of all living organisms.
- 3. Protein, Protein that moves substances or wastes through the plasma membrane.
- 6. A part of the eukaryotic cell containing DNA and RNA and responsible for growth and reproduction; controls the activities of the cell.
- 7. Apparatus, Flattened stack of proteins that modifies, sorts and packages proteins into acid sacs called vesicles.
- 8. The substance found in living cells (outside the nucleus), where chemical reactions take place
- 9. Transport, the movement of substances against a concentration gradient; requires energy.
- 11. The natural movement of particles from an area of high concentration to an area of low concentration
- 12. Site of rRNA production.
- 15. Cells with a nucleus and membrane bound organelles.
- 17. Gradient, the amount of substance in a given volume, normally measured in units of mol/dm3
- 20. The movement of water, through a partially permeable membrane, into a solution with a lower water concentration
- 22. Membrane, A semipermeable membrane that only allows certain substances to pass in and out of a cell.
