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 |
