Photosynthesis Vocab
Vocabulary Practice for the process of photosynthesis
| Term | Definition |
|---|---|
| Photosynthesis | The process by which plants convert solar energy into chemical energy |
| Light dependent reactions | The first stage of photosynthesis which involves the use of light energy to split water, generating oxygen gas, ATP, and NADPH |
| Inputs of the light dependent reaction | Light, Water, ADP, and NADP+ |
| Outputs of the light dependent reaction | Oxygen, ATP, and NADPH |
| Word equation for photosynthesis | carbon dioxide + water + light --> glucose + oxygen |
| Light independent reactions | the second stage of photosynthesis which uses energy stored in ATP and NADPH to "fix" carbon dioxide into a more usable form and ultimately produces glucose |
| Inputs of the light independent reaction | Carbon dioxide, ATP, and NADPH |
| Outputs of the light independent reaction | Glucose, ADP, and NADP+ |
| Chloroplast | The organelle found in plants cells in which photosynthesis occurs |
| Chlorophyll | The pigment found in the thylakoid disc of a chloroplast that captures light energy |
| Thylakoid disc | The location of the light dependent reactions |
| Stroma | The location of the light independent reactions |
| Energy conversion that occurs in photosynthesis | solar energy to chemical energy |
| Inputs of photosynthesis | carbon dioxide, water, and light |
| Outputs of photosynthesis | glucose and oxygen |
| Autotrophs | organisms that do photosynthesis- they capture solar energy and convert it to chemical energy in the form of glucose |
| Granum | a stack of thylakoid discs |
| Leaves | plant organ that contains chloroplasts in high concentrations for photosynthesis to occur |
| Stomata | Pores, or openings on the leaves of plants to allow for the diffusion of gases--oxygen out and carbon dioxide in. |
| Calvin Cycle | The other name for the light independent reactions. |
| ATP | adenosine triphosphate-a high energy molecule |
| NADPH | electron carrying molecule that transfer electrons from the light dependent reaction to the light independent reaction. |
