Photosynthesis Review
What is the chemical equation for photosynthesis?
6CO2 + 6H2O + Sunlight -> C6H12O6 + 6O2
Photosynthesis
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).
Glucose
A simple sugar molecule with stored chemical energy used by plants as their energy source; one of the main products of the photosynthesis process.
Products
A substance produced during a chemical reaction.
Reactants
A substance that takes part in and undergoes change during a reaction.
Where photosynthesis takes place
Chloroplasts
Radiant Energy
Energy from the Sun that reaches Earth as visible light, ultraviolet light, and infrared radiation (heat).
Chemical Energy
Energy stored in the particles that make up food, fuel, and other matter, which is released during a chemical reaction such as burning wood, or the reactions that occur in the cells of organisms.
What are the products of photosynthesis?
Glucose and oxygen
Photosynthesis
Green plants capture and store light energy from the Sun through the process of -
How is the process of photosynthesis considered a chemical equation?
Photosynthesis begins with molecules of water and carbon dioxide and when light is added the molecules break apart to rearrange into new molecules of glucose and oxygen.
Glucose
Photosynthesis produces the chemical energy that a plant's cells need. What form does this chemical energy take?
Convert radiant energy into chemical energy
Plants use photosynthesis to meet their survival needs by enabling them to -
The form in which chemical energy is stored during photosynthesis
Sugar (glucose)
What are the reactants of photosynthesis?
Sunlight (radiant energy), water, and carbon dioxide
Radiant energy
The Sun contributes to photosynthesis by providing plants with -
Chlorophyll
The green pigment involved in photosynthesis
Chemical Reaction
The process by which one or more substances change to produce one or more different substances.
Why is photosynthesis important to humans?
This process provides food for nearly all life on Earth and it provides the oxygen humans need to breathe
Where does carbon dioxide enter and oxygen leave the plant?
Through the stomata in the plant's leaves
How does a plant lose water through transpiration?
Water is released and evaporated through the stomata in leaves.
Oxygen
What gas do plants release as a result of photosynthesis?
