6. is the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment.
8. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
11. a colorless, odorless gas produced by burning carbon and organic compounds and by respiration.
13. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
14. where photosynthesis takes place.
15. each surrounded by a pair of guard cells, are microscopic pores in the shoot epidermis of plants.

1. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
2. is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
3. is a chemical element with an atomic number of 8 (it has eight protons in its nucleus). Oxygen forms a chemical compound (O2) of two atoms which is a colorless gas at normal temperatures and pressures
4. Blood sugar is the main sugar found in your blood
5. 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).
7. an organism that eats other plants or animals for energy and nutrients
9. is a substance that is present at the end of a chemical reaction.
10. A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA.
12. a substance that takes part in and undergoes change during a reaction.
13. 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.
