photosynthesis Flashcards
photosynthesis
a chemical reaction during which plants convert energy from the sun to chemical energy;the reaction converts carbon dioxide and water to sugar and oxygen
carbon dioxide
a clear odorless gas which plants use as a raw material in photosynthesis
reactants
a substance that takes part in and under goes change during a reaction
radiant energy
energy from the sun that reaches earth as visible light,ultraviolet light,and infrared radiation
chemical energy
energy that is stored within a molecule
chloroplast
organelle in plant cells used to make food.it contains a light trapping pigment called chlorophyll
chlorophyll
a light trapping pigment in the chloroplasts of plan cells
glucose
a simple sugar made by plants during photosynthesis.plants store long chains of glucose as starch
starch
long chains of glucose stored in plants
Products
A substance produced as a result of a chemical change
Oxygen
A clear colorless gas that is a waste product of plants during photosynthesis
Turgor pressure
The pressure,or force of the water inside a plant cell against the outside,or cell wall
Geotropism
The response of a plant to gravity
Phototropism
The growth of a plant toward or away from light
