  • Which form of energy is used to power photosynthesis; thermal, chemical, nuclear, radiant?
    Radiant
  • The process of photosynthesis captures solar energy, converts it to a chemical energy, and stores it in the bonds of---
    glucose
  • What is a chemical reaction during which plants convert radiant energy from the Sun to chemical energy; a reaction that converts carbon dioxide and water to sugar (glucose)?
    Photosynthesis
  • What type of energy is from the sun that reaches Earth as visible light, ultraviolet light, and infrared radiation (heat)?
    Radiant energy
  • What is the simplest unit of a chemical compound that can exist; formed when two or more atoms join together chemically?
    Molecule
  • A plant underwater is producing bubbles. What is the identity of the gas in the bubbles?
    Oxygen
  • What is energy stored in the particles that make up food, fuel, and other matter, which are released during a chemical reaction such as burning wood, or the reactions that occur in the cells of organisms?
    chemical energy
  • What is a simple sugar molecule with stored chemical energy used by plants as their energy source; one of the main products of the photosynthesis process?
    Glucose
  • Are plants autotrophs or heterotrophs?
    Autotrophs
  • What is the smallest particle of an element maintaining the chemical identity of that element?
