Photosynthesis Flashcards
Photosynthesis
A chemical reaction during which plants convert energy from the Sun to the 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 undergoes change during a reaction
Radiant Energy
Energy from the sun that reaches Earth as visible light, ultraviolet light, and infared radiation (heat)
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 plant 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 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
