Plants 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
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
Reactants
a substance that takes part in and undergoes change during a
reaction
Chlorophyll
a light-trapping pigment in the chloroplasts of plant cells
Chloroplasts
organelle in plant cells used to make food. It contains a light
trapping pigment called Chlorophyll.
Carbon dioxide
- a clear odorless gas which plants use as a raw material in
photosynthesis
Products
a substance produced as a result of a chemical change
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
Oxygen
a clear colorless gas that is a waste product of plants during
photosynthesis
Turgor pressure
he pressure, or force of the water inside a plant cell
against the outside, or cell wall
Geo-tropism
the response of a plant to gravity
Phototropism
the growth of a plant toward or away from light
