Here is the matching of the words to the definitions:
1. **ADP** - adenosine di-phosphate; a lower energy, intermediate molecule used to convert to ATP by adding a third phosphate group.
2. **ATP** - adenosine tri-phosphate: a molecule that carries energy inside cells and is the energy currency of the cell; a product of the light-dependent reactions of photosynthesis.
3. **ATP synthase** - A protein that creates ATP from ADP during photosynthesis.
4. **Chlorophyll** - Green pigment that captures the energy from the sun.
5. **Chloroplast** - Organelle in a green plant cell that conducts photosynthesis.
6. **Electron transport chain** - System by which high-energy electrons are moved to photosystem I and hydrogen ions are pumped into the inside of the thylakoid during photosynthesis.
7. **Light dependent reactions** - A series of reactions that take the light energy that is captured by the chlorophyll and convert it into chemical energy in the form of NADPH and ATP; consists of photosystem II, the electron transport chain, photosystem I and hydrogen ion movement and formation of ATP.
8. **Calvin cycle** - A series of reactions that do not require the presence of light energy and that take the carbon from carbon dioxide and convert it to carbohydrates (glucose), amino acids, and other compounds.
9. **NADP+** - Nicotinamide adenine dinucleotide phosphate; an electron carrier molecule that accepts two high energy electrons and one hydrogen ion to become NADPH.
10. **NADPH** - Nicotinamide adenine dinucleotide phosphate hydrogen; a product of the light dependent reactions of photosynthesis used to power some of the reactions in the light independent stage of photosynthesis.
11. **Photosynthesis** - Process that transforms light energy into stored chemical energy.
12. **Photosystem I** - Protein complex where the transfer of hydrogen ions to NADP+ to make NADPH occurs during photosynthesis.
13. **Photosystem II** - Protein complex where light is absorbed, water is split, hydrogen ions are created, and oxygen is released during photosynthesis.
14. **Stroma** - Fluid-filled space that surrounds the stacks of thylakoids inside the chloroplast within which the light independent reactions of photosynthesis occur.
15. **Thylakoid** - Sack-like structure surrounded by a membrane inside chloroplasts where the light dependent reactions of photosynthesis occur.
