Photosynthesis
7.5A Photosynthesis
Term | Definition |
---|---|
RADIANT ENERGY | Energy from the sun that reaches earth as visible light, & ultraviolet/infrared (heat) radiation. |
CHEMICAL ENERGY | Energy stored in chemical bonds & released through chemical reactions. |
PHOTOSYNTHESIS | Chemical reaction in which plants convert Sun's radiant energy into chemical energy; converts carbon dioxide & water into glucose & oxygen; photo=light. |
CHEMICAL REACTION | Process by which 2 or more chemical substances interact & are chemically changed, producing different chemical substances. |
REACTANT | Substance that takes part in & undergoes change during a reaction. |
PRODUCT | Substance produced during a chemical reaction. |
GLUCOSE | Simple carbohydrates produced by photosynthesis; used to store energy & build structural molecules. |
ATOM | Smallest particle of an element, made of electrons, protons, & neutrons. |
MOLECULE | Simplest unit of a chemical compound that can exist, formed when 2 or more atoms join together chemically. |
LAW OF CONSERVATION OF MATTER | Matter is neither created nor destroyed but can only be transformed. |
OXYGEN | Colorless, odorless, reactive gas and life-supporting component of air; waste product of photosynthesis. |
CARBON DIOXIDE | Colorless, odorless gas produced by burning carbon and organic compounds and by respiration; naturally present in air and is absorbed by plants in photosynthesis. |
CARBOHYDRATES | Any of a large group of organic compounds occurring in foods and living tissues, including sugars, starch, and cellulose. |
STOMATA | Small openings on the underside of a leaf through which oxygen and carbon dioxide can move. |
CHLOROPLAST | Organelle found in plant and algae cells where photosynthesis occurs. |
CHLOROPHYLL | Green pigment in plants that absorbs light energy used to carry out photosynthesis. |
WATER | Colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms, reactant of photosynthesis. |
