|
|
Term
|
Definition
| Obtain energy from the foods they consume. |
|
|
Term
|
Definition
| One of the principal chemical compounds that cells use to store and release energy. Consists of adenine, a 5-carbon sugar (ribose), and three phosphate groups. |
|
|
Term
|
Definition
| the process in which plants use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates-sugars and starches- and oxygen, a waste product. |
|
|
Term
|
Definition
| plants gather the sun's energy with light-absorbing molecules called pigments. |
|
|
Term
|
Definition
| The plant's principal pigment. |

Term
|
Definition
| light-collecting units of the chloroplast |
|
|
Term
|
Definition
| region outside the thylakoid membranes in chloroplasts |
|
|
Term
|
Definition
| one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules |
|
|
Term
| light-dependent reactions |
|
Definition
| reactions of photosynthesis that use energy from light to produce ATP and NADPH |
|
|
Term
|
Definition
| large protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP |
|
|
Term
|
Definition
| reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars |
|
|
Term
| What is the basic energy source of all cells? |
|
Definition
|
|
Term
| What do light-dependent reactions do? |
|
Definition
| produce oxygen gas and convert ADP and NADP+ into ATP and NADPH. Occur in thylakoid. |
|
|
Term
| What does the Calvin cycle do? |
|
Definition
| uses ATP and NADPH from the light-dependent reactions to produce high-energy sugars. Light-independent reactions. |
|
|
Term
|
Definition
| Uses bell jar, candle, and plant to find that plants release oxygen |
|
|
Term
|
Definition
| Concludes that trees gain most of their mass from water |
|
|
Term
|
Definition
| finds that aquatic plants produce oxygen bubbles in the light but not in the dark. Concludes that plants need sunlight to produce oxygen. |
