photosynthesis and cellular respirtation

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.

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.
