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