Across
- 1. An organism that produces organic compounds from simple substances such as water and carbon dioxide.
- 3. A compound consisting of an adenosine molecule bonded to three phosphate groups, present in all living tissue. The breakage of one phosphate linkage provides energy for physiological processes such as muscular contraction.
- 5. A simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
- 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.
- 7. A plastid that contains chlorophyll and in which photosynthesis takes place.
- 9. A process in which oxygen is used to make energy from carbohydrates.
Down
- 1. 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. 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.
- 4. An organism,especially a soil bacterium, fungus, or invertebrate that decomposes organic material.
- 8. An organism that derives the organic compounds and energy it needs from the consumption of other organisms.
