Biology Chp.3- Chp.8
| Question | Answer |
|---|---|
| What are the 3 different types of energy? | light, heat and electricity |
| Why do we need energy to survive? | In order for our bodies to be able to work |
| What is the structure of ATP? | Adenine, Ribose and 3 Phosphate Groups |
| Where does photosynthesis take place? | chloroplasts |
| Why do we care that plants photosynthesize? | We need plants because they give us oxygen and they need us because we give out carbon dioxide. |
| What are the different names for the reactions in photosynthesis? | light dependent and light independent reactions |
| What is the visible light spectrum? | The visible light spectrum is the things that we can see with our naked eye. |
| What colors to plants absorb/reflect? | Plants absorb all colors except green which they reflect. |
| How do pigments aid in photosynthesis? | Pigments aid in photosynthesis by absorbing energy for the plant to use. |
| Where are these pigments found? | These pigments are found in the leaves. |
| What are the different structures in a chloroplast? | stroma, thylakoids (granum) |
| What is the balanced chemical equation for photosynthesis? | 6CO2 + 6H2O --[light]--> C6H12O6 + 6O2 |
| What occurs in the light dependent reactions? | H2O+sunlight-->O2+stored energy (takes place in the thylakoids) |
| What occurs in the light independent reactions? | CO2+stored energy--> C6H12O6 (glucose) (takes place in the stroma) |
| ATP (adenosine triphosphate) | compound used by cells to store and release energy |
| heterotroph | organism that obtains food by consuming other living things (ex. us! ) |
| autotroph | organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds |
| photosynthesis | process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as starches and sugars |
| pigment | light absorbing molecules used by plants to gather the sun's energy |
| chlorophyll | principal pigment of plants and other photosynthetic organisms |
| thylakoid | saclike photosynthetic membranes found in chloroplasts |
| stroma | fluid portion of the chloroplast; outside of the thylakoids |
| NADP+ | (nicotinamide adenine dinucleotide phosphate) carrier molecule that transfers high energy electrons from chlorophyll to other molecules |
