Across
- 1. This is the energy source for the reaction
- 6. These leaf cells have large gaps around them for gases to move freely
- 7. The product of photosynthesis can also be used to make this type of molecule
- 12. The gas needed for photosynthesis
- 13. The movement of a substance from a high to low concentration
- 14. The reaction in plants that makes their ‘food’
- 16. This gas is produced by photosynthesis
- 17. The gas produced by photosynthesis is needed for this reaction in the mitochondria of our cells
- 19. These are the holes on the underside of the leaf
- 21. The waxy top surface of the leaf
- 25. These are organisms that produce their own food using photosynthesis
- 27. These are green organelles found in cells
Down
- 2. This limiting factor of photosynthesis affects how well enzymes work and if they become denatured
- 3. e.g. grass -> rabbit -> fox
- 4. These surround the holes under the leaf and control whether they are open or closed
- 5. This type of reaction is when the products have more energy than the reactants
- 8. This is the ‘food’ made by photosynthesis
- 9. This limiting factor of photosynthesis depends on what is available in the air
- 10. Something that eats something else in a food chain
- 11. This limiting factor of photosynthesis depends on the sun, for example
- 15. The total mass in organisms, usually shown as the mass after drying
- 18. This is taken into root hair cells by osmosis
- 20. An animal that only eats plants
- 21. This is the green pigment in chloroplasts that absorbs light energy
- 22. When carbon dioxide diffuses in and oxygen diffuses out the leaf, for example
- 23. Plants in a food chain are also known as…
- 24. Glucose can be stored away in the plant as this
- 26. These leaf cells are packed with lots of chloroplasts
