Across
- 1. Diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.
- 3. the act or process of burning.
- 4. A microscopic organism, esp. a bacterium, virus, or fungus.
- 7. The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
- 13. The process or action by which one thing absorbs or is absorbed by another: "shock absorption".
- 14. diffusion Transport of substances across a biological membrane from an area of higher concentration to an area of lower concentration by means of a carrier molecule. Since the substances move along the direction of their concentration gradients, energy is not required.
- 16. transport The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
- 17. Something put into a system or expended in its operation to achieve output or a result,
- 18. A member of a large group of unicellular microorganisms lacking organelles and an organized nucleus, including some that can cause disease.
- 19. A substance that provides nourishment essential for growth and the maintenance of life.
- 21. the metabolic processes whereby certain organisms obtain energy from organic molecules.
- 22. A line that marks the limits of an area; a dividing line
- 24. something, such as a liquid or gas, that flows in
- 25. Respiration the oxidation of organic compounds that occurs within cells, producing energy for cellular processes.
- 28. transport transport of a substance across a cell membrane by diffusion; expenditure of energy is not required.
Down
- 1. An individual animal, plant, or single-celled life form
- 2. A group of interacting, interrelated, or interdependent elements forming a complex whole.
- 3. the act of concentrating; the state of being concentrated.
- 5. force a force which is the result of two or more forces acting conjointly, or a motion which is the result of two or more motions combined.
- 6. Take in or soak up (energy, or a liquid or other substance) by chemical or physical action, typically gradually.
- 7. Synthesize sugars or other substances by means of photosynthesis.
- 8. Reaction A process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form Compound
- 9. Get, acquire, or secure (something):
- 10. The process of becoming smaller.
- 11. A member of a large group of unicellular microorganisms lacking organelles and an organized nucleus, including some that can cause disease.
- 12. The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.
- 15. Of or relating to the properties of spheres
- 20. The first trophic level in a food chain in which it serves as a food source for consumers or for higher trophic levels.
- 23. to make a solution of, as by mixing with a liquid; pass into solution
- 26. reproduction reproduction without the fusion of gametes
- 27. Consisting of many different and connected parts.
