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
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 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
product
a substance produced as a result of a chemical change
oxygen
a clear colorless gas that is a waste product of plants during photosynthesis
geotropism
the response of a plant to gravity
Phototropism
the growth of a plant toward or away from light
Turgor Pressure
the pressure, or force of the water inside a plant cell
against the outside, or cell wall
