Photosynthesis Overview
• How plants create energy.• The process by which plants take in CO2 and
H2O in the presence of sunlight to produce chemical energy using Chlorophyll.
• Reactants = CO2 + H2O + light energy must also be present but is not considered a reactant.
• Products = Sugar (C6H12O6) + O2
Photosynthesis Reactants
• Plants get CO2 from the air through tiny holes in leaves.
• Plants get H2O from the ground using roots to draw it up.
• They get energy form the sun. (Electromagnetic)
• Chlorophyll is necessary for plants to carry out Photosynthesis.
Photosynthesis Products
• Plants release Oxygen through the same tiny holes that they take in carbon dioxide.
• Photosynthesis also produces sugar (C6H12O6).
Photosynthesis Sugar
• What is the sugar used for?
• To grow (stems, leaves, branches, etc.)
• To reproduce (fruit, seeds, shoots, pollen, etc.)
• For protection (poisons, toxins, armor, spikes, thorns, etc.)
Draw Photosynthesis
• On the back of your notes draw the process of photosynthesis.

Why is Photosynthesis so important?
• Write down at least 2 reasons.
Why is Photosynthesis so important?
• It is the only way to convert the suns energy into food.
• The sun is the source of almost all energy on Earth.
• It also purifies our air taking out poisonous CO2 and replacing it with Oxygen.
• Without photosynthesis everyone and everything would die.
