Across
  1. 2. The protein-rich semiliquid material in the interior of a chloroplast.
  2. 6. The light-absorbing green-coloured pigment that begins the process of photosynthesis.
  3. 9. Requiring the presence of air or free oxygen for life
  4. 10. A nonmetallic element that exists in its free form as a colorless, odorless gas and makes up about 21 percent of the Earth's atmosphere.
  5. 12. Pores on the leaf where O2 exits and CO2 enters
  6. 13. The biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
  7. 14. Long-term shifts in temperatures and weather patterns
  8. 17. The state when two solutions have equal concentration of solutes across a semipermeable membrane
  9. 19. The long-term warming of the planet's overall temperature
  10. 21. The process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere
Down
  1. 1. A process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.
  2. 3. Gases in the earth's atmosphere that trap heat.
  3. 4. Converts light energy to the chemical energy of food
  4. 5. A membrane-bound organelle in green plant and algal cells that carries out photosynthesis.
  5. 7. A packet of light.
  6. 8. A biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere
  7. 11. The chief source of energy for living organisms.
  8. 15. A colorless, odorless gas
  9. 16. A molecule containing three high energy phosphate bonds that acts as the primary energy-transferring molecule in a living organism.
  10. 18. The continuous movement of water within the Earth and atmosphere
  11. 20. Living in the absence of air or free oxygen
