Photosynthesis
| Question | Answer |
|---|---|
| Organisms that make their own food | autotrophs |
| Organisms that cannot make their own food they get energy from eating | heterotrophs |
| Example of a heterotroph | animal / human |
| Example of a autotroph | plant / tree |
| ATP and ADP are made up of three molecules | adenine / ribose / phosphates |
| ATP releases energy by giving up a | phosphate |
| VanHelmont found that plants mass comes from | water |
| Priestly and Ingenhousz found plants needed what to grow | light |
| Ingenhousz proved plants need light to produce | oxygen |
| takes light energy and converts it into chemical energy | photosynthesis |
| Photosynthesis needs (reactants) | sunlight / carbon dioxide / water |
| Photosynthesis produces (products) | oxygen / high energy sugars |
| In photosynthesis 6 Carbon Dioxide is converted into | 6 Oxygen |
| Light absorbing molecules | pigments |
| Plants absorb the suns energy by absorbing | sunlight |
| Plants don't absorb what color light | green |
| Chlorophyll is found in the | thylakoid |
| Stack of thylakoids | granum |
| Stroma is the structure that surrounds the | thylakoids |
| Smallest to largest in Choroplast | pigment/chlorophyll/thlakoid/ granum/stroma/chlorplast |
| Light Dependent Reactions take place in the | thylakoid membranes |
| Where does photosynthesis begin | Pigments (photosystems II) |
| Products of Light Dependent reaction | oxygen/ATP/NADPH |
| ETC, photosystems, ATP synthase all take place in the | thylakoid membrane |
| Why does the Thylakoid membrane become + charged during light reaction | H+ ions are realeased |
| Photsystem I and II are found in the | thylakoid membrane |
| Dark Cycle is also called | Calvin Cycle |
| Calvin Cylcle takes place in the | stroma |
| Reactants of Calvin Cycle | Carbon Dioxide/ATP/NADPH |
| Products of Calvin Cycle | Sugars/ADP/NADP |
| Light/ Amount of Water / temp all affect the | rate of Photosynthesis |
