Photosynthesis Vicab Flashcards
Organisms that can use the energy in sunlight to convert carbon dioxide and water I to carbon compounds
Photoautotrophs
Organisms that can make their own food
Autotrophs
Organisms that can use the energy from chemical reactions to convert carbon dioxide into other carbon compounds
Chemoautotrphs
Organisms that must obtain their energy by eating autotrophs or other heterotrophs
Heterotrophs
One of the principal chemical compounds that cells use to store and release energy
Adenosine triphosphate
The process of using the energy of sunlight to convert water and carbon dioxide into high energy sugars and oxygen
Photosynthesis
Light absorbing molecules
Pigments
The green pigment that allows plants to absorb light for use in photosynthesis
Chlorophyll
An organelle found in plants and some Protista where photosynthesis takes place
Chloroplasts
Saclike photosynthetic membranes where the light dependent reactions of photosynthesis takes place
Thylakoids
Stacks if thylakoids
Grana
Clusters of chlorophyll and other pigments organized by proteins that collect the light needed for photosynthesis
Photosystems
The region inside the chloroplasts that lies outside of the thylakoids
Stroma
An electron carrier molecule that moves the electrons that have been excited by the sunlight during the light dependent reaction to the light independent reaction
NADPH
Produces oxygen gas and convert ADP and NADP+ into energy carrying ATP and NADPH; takes place in the thylakoids
Light dependent reaction
