- 9. has a lower solute concentration compared to the intraceullular solute concentration
- 10. the source of energy for use and storage at the cellular level
- 11. an energy driven process where membrane proteins transport molecules across cells
- 13. a type of sugar, the chief source of energy for living organisms
- 14. the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
- 16. movement of a solute from a region of high electrochemical potential on one side of the cell membrane to a region of lower electrochemical potential on the opposite side
- 17. a repeating cycle of processes during which nitrogen moves through both living and non living things
- 19. the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere

Down
- 1. the long term warming of the plant's overall temperature
- 2. chemical process in which oxygen is used to make energy from carbohydrates
- 3. nature's way of reusing carbon atoms,which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again
- 5. respiration using electron acceptors other than molecular oxygen.
- 7. a colorless, odorless gas
