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.
Radiant energy
Energy from the sun that reaches Earth as visible light,ultraviolet light, and infrared 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 chloroplast of plant cells.
Glucose
A simple sugar made by plants during photosynthesis. Plants store long chains of glucose as starch.
Reactants
A substance that takes part in and undergoes change during a reaction.
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 towards or away from light.
