Across
  1. 4. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
  2. 5. a thing or person that is the result of an action or process
  3. 7. the main sugar found in your blood
  4. 9. a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
  5. 10. a substance that takes part in and undergoes change during a reaction
  6. 11. tiny, microscopic and critical for photosynthesis.
  7. 13. a series of chemical reactions that break down glucose to produce ATP
  8. 14. reaction a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
  9. 15. a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
  10. 16. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

  1. 1. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
  2. 2. A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA.
  3. 3. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
  4. 6. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring
  5. 8. the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment
  6. 12. an organism deriving its nutritional requirements from complex organic substances.
