Term
Autotrophs
Definition
Organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds: also called a producer.
Term
Heterotroph
Definition
Organism that obtains energy from the foods it consumes; also called a consumer.
Term
Adenosine Triphosphate (ATP)
Definition
Adenosine Triphosphate (ATP) One of the principal chemical compounds that living things use to store and release energy.
Term
Photosynthesis
Definition
Plants use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates -sugar and starches and oxygen a wast product.
Term
Pigments
Definition
Plants gather the sun's energy with light absorbing molecules.
Term
Chlorophyll
Definition
Principal pigment of plants and other photosynthetic organisms; captures light energy.
Term
Thylakiods
Definition
Saclike photosynthetic membrane found in chloroplasts.
Term
Photosystems
Definition
Light-collecting units of the chloroplast.
Term
Stroma
Definition
Region outside the thylakoid membranes.
Term
NADP+ (Nicotinamide Adenine Dinucleotide Phosphate)
Definition
One of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules.
Term
Light-Dependent Reactions
Definition
Produce oxygen gas and convert ADP and NADP+ into the energy carriers ATP and NADPH.
Term
ATP Synthase
Definition
Large protein that uses energy from H+ ions to bind ADP and a phosphate grop together to produce ATP.
Term
x
Definition
Term
Calvin Cycle
Definition
Plants use the energy that ATP and NADPH from the light-dependent reactions to produce high-energy sugars.
