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 undergoes change during a reaction.
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.
Starch
long chains of glucose stored in plants
Products
a substance produced as a result of a chemical reaction.
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
