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 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 at a visible light
chemical energy
energy that is stored within a molecule
chloroplast
organelle in plant cells used to make food.
chlorophyll
a light trapping pigment in the chloroplast of plant cells
glucose
a simple made by plants doing photosynthesis also a sugar
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 waste during photosynthesis
turgor pressure
the pressure, or force of the water inside a plant cell against the outside, or cell war
geotropism
the response of plant gravity
phototropism
the growth of plant toward or way from light
