- 3. It plays a crucial role in many of the chemical reactions that make up the procedure of the photosynthesis.
- 5. the natural colouring matter of animal or plant tissue.
- 7. of a class of mainly yellow, orange, or red fat-soluble pigments, including carotene, which give colour to plant parts such as ripe tomatoes and autumn leaves.
- 8. 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.
- 9. a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.
- 10. organism deriving its nutritional requirements from complex organic substances.
Down
- 1. Cycle: is a process that plants and algae use to turn carbon dioxide from the air into sugar
- 2. process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
- 4. organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
- 6. green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.
