Calvin cycle- cycle in plants that makes sugar from carbon dioxide, H+ ions, and high-energy electrons carried by NADPH (Concept 8.1)</p><p>7. wavelength- distance between adjacent waves (Concept 8.2)</p><p>8. electromagnetic spectrum- range of types of electromagnetic energy from gamma waves to radio waves (Concept 8.2)</p><p>9. pigments- chemical compound that determines a substance's color (Concept 8.2) </p><p>10. paper chromatography- laboratory technique used to observe the different pigments in a material (Concept 8.2)</p><p>11. photosystems- cluster of chlorophyll and other molecules in a thylakoid (Concept 8.2)</p><p>12. Carbon cycle- process by which carbon moves from inorganic to organic compounds and back (Concept 8.4)</p><p>13. greenhouse effect- process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space (Concepts 8.4, 36.4) </p>
