Terms in this set (23)
Organisms that make their own food
Organisms that cannot make their own food directly from the sun
*Plants and some other types of organisms are able to use __________ to produce food.
light energy from the sun
adenosine triphosphate - One of the principal chemical compounds that cells use to store and release energy
*The characteristics of ATP make it exceptionally useful as _________________
the basic energy source of all cells
Conversion of light energy from the sun into chemical energy.
Jan van Helmont
___ studied the mass of soil in comparison to how high a plant grew.
English chemist who discovered oxygen, discovered that plants release oxygen
*The experiments performed by _________
led to work by other scientists who discovered that int he presence of light, plants transform carbon dioxide and water into carbohydrates and they also release oxygen
this scientist redid the candle under a jar experiment and found that the candle only stayed lit with the plant if it was exposed to light
*Photosynthesis uses _______________ to convert _______________ and _____________ into high energy sugars and oxygen
energy of sunlight
water and carbon dioxide
*In addition to water and carbon dioxide, photosynthesis requires _________ and ______________, a molecule in chloroplasts.
light and chlorophyll
Colored chemical compounds that absorb light
Green pigment in plants that absorbs light energy used to carry out photosynthesis
Saclike photsynthetic membrane
light-collecting units of the chloroplast
Region outside the thylakoid membranes in chloroplasts.
(nicotinamide adenine dinucleotide phosphate) one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
light dependent reactions
Set of reactions in photosynthesis that use energy from light to produce ATP and NADPH
*The light dependent reactions produce ___________ and convert ADP and NADP+ into the enengergy carriers _____________ and _______________
ATP and NADPH
A membrane protein called _________________________ allows H+ ions to pass through the thylakoid membrane.
cycle in photosynthesis where plants use the energy that ATP and NADPH contain from the light dependent reactions to build high-energy sugars that can be stored for a long time
