| 229783194 | Autotroph | Organisms such as plants which make their own food. | |
| 229783195 | Heterotrophs | Organisms such as animals that cannot use the sun's energy directly. They obtain energy from the foods they consume. | |
| 229783196 | Adenosine Triphosphate (ATP) | A principal chemical compound that cells use to store and release energy. | |
| 229783197 | Photosynthesis | A process where plants use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates-- sugars and starches -- and oxygen, a waste product. | |
| 229783198 | Pigment | Light-absorbing molecules that plants use to gather the sun's energy. | |
| 229783199 | Chlorophyll | The plants' principal pigment. Two main types of chlorophyll: chlorophyll a and chlorophyll b. | |
| 229783200 | Thylakoids | Saclike photosynthetic membranes that are in chloroplasts. | |
| 229783201 | Photosystems | Proteins in the thylakoid membrane organize chlorophyll and other pigments into clusters, which are known as these. | |
| 229783202 | Stroma | The place where the Calvin cycle takes place, which is the region outside the thylakoid membranes. | |
| 229783203 | NADP+ (Nicotinamide Adenine Dinucleotide Phosphate) | A carrier molecule that is a compound known as this. It accepts and holds 2 high-energy electrons along with a hydrogen ion (H+) which converts the NADP+ into NADPH | |
| 229783204 | Light-dependent reactions | These reactions require light. They use energy from light to produce ATP and NADPH. | |
| 229783205 | ATP synthase | The cell membrane contains this protein that spans the membrane and allows H+ ions to pass through it. | |
| 229783206 | Calvin Cycle | When plants use the energy that ATP and NADPH contain to build high-energy compounds that can be stored for a long time. |
