Photosynthesis

2. A yellow, orange or red plant pigment used as an accessory pigment in photosynthesis
3. A green pigment responsible for light capture in photosynthesis in algae and plants
6. A cluster of light-harvesting accessory pigments surrounding a primary pigment or reaction center
7. A reaction in which a complex molecule is broken down to simpler ones, involving the addition of water
8. Photosynthetic organelle in eukaryotes
10. A pigment that is not essential to photosynthesis but which absorbs light of different wavelengths and passes the energy to chlorophyll a
12. A pore in the epidermis of the leaf, bounded by two guard cells
14. Adenine diphosphate
15. The process by which bacteria uses energy from inorganic substances are used to make sugars

1. "Packets" of energy that travel in waves which compose light
2. A cycle of reactions in photosynthesis in which carbon dioxide is fixed into carbohydrate
4. The reaction which converts light energy into chemical energy
5. The splitting of water using light energy
9. An organism that cannot produce its own food, instead taking nutrition from other sources
10. An organism that can trap an inorganic carbon source using energy from light or from chemicals
11. The matrix of chloroplast in which the light independent reactions of photosynthesis occur
13. The product formed from photosynthesis which plants use as food
