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 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 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 change
oxygen
a clear odorless gas that is 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
geo tropism
the response of a plant to gravity
phototropism
the growth of a plant toward or away from light
