Photosynthesis

4. green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis.
5. Process by which ATP is synthesized by using chemicals as an energy source
8. The process by which cells break down simple food molecules to release the energy they contain.
9. organism that makes its own food.
11. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis.
12. splitting water by light; produces the hydrogen ions and electrons used in light reactions and oxygen atoms.
14. within the chloroplast, consists of sac-like membranes, known as thylakoid membranes.
15. second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NADPH, to make glucose.
16. first stage of photosynthesis in which light energy from the sun is captured and changed into chemical energy that is stored in ATP and NADPH.

1. main energy source that cells use for most of their work
2. simple sugar that all living things use to store and transport energy.
3. flattened sac of membrane inside a chloroplast where the first stage of photosynthesis (light reactions) occurs.
6. fluid-filled space inside a chloroplast where the second stage of photosynthesis (Calvin cycle) occurs.
7. molecules that accept and temporarily hold high-energy electrons.
10. Conversion of light energy from the sun into chemical energy.
13. short-term energy carrier; temporarily stores energy during photosynthesis.
