2. the second of the two major stages in photosynthesis
4. an organelle found in plants and photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic compounds from carbon dioxide and water
6. that portion of the electromagnetic spectrum that can be detected as various colors by the human eye
8. an organism that obtains organic food molecules by eating other organisms or substances derived from them
11. in the thylakoid membrane of a chloroplast or in the membrane of some prokaryotes, a specialized molecule that shares the reaction-center complex with a pair of chlorophyll a molecules and that accepts an electron from them
15. the conversion of light energy to chemical energy that is stored in sugars or other organic compounds
17. an organism that obtains organic food molecules without eating other organisms or substances derived from other organisms
18. a route of electron flow during the light reactions of photosynthesis that involves both photosystems and produces ATP, NADPH, and O2

1. a light-capturing unit located in the thylakoid membrane of the chloroplast or in the membrane of some prokaryotes
3. a route of electron flow during the light reactions of photosynthesis that involves only one photosystem and that produces ATP but no NADPH or O2
5. the first of two major stages in photosynthesis
7. a metabolic pathway that consumes oxygen and ATP, releases carbon dioxide, and decreases photosynthetic output
9. a three-carbon carbohydrate that is the direct product of the Calvin cycle
10. the distance between crests of waves
12. a quantum, or discrete quantity, of light energy that behaves as if it were a particle
13. the dense fluid within the chloroplast surrounding the thylakoid membrane and containing ribosomes and DNA
14. a green pigment located in membranes within the chloroplasts of plants and algae and in the membranes of certain prokaryotes
16. the reduced form of nicotinamide adenine dinucleotide phosphate
