- 2. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis
- 4. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
- 7. a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
- 9. a plastid that contains chlorophyll and in which photosynthesis takes place.
- 11. An organism that manufactures its own food from inorganic substances, such as carbon dioxide and ammonia
- 13. any coloured material found in a plant or animal cell.
Down
- 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
- 3. each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
- 5. a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
- 6. is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.
- 8. a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
- 10. The cells and tissues that support and give structure to organs, glands, or other tissues in the body
- 12. light from the sun.
