Photosynthesis 1
The process that uses energy from the sun to make food from water and carbon dioxide.
What is photosynthesis?
A gas made from one atom of carbon, 2 atoms of oxygen.(CO2)
What is a carbon dioxide?
What are the reactants in photosynthesis
carbon dioxide and water
What part of the plants absorbs carbon dioxide?
Leaves
Living organisms that use photosynthesis
plants
Gas removed from the atmosphere during photosynthesis.
What is carbon dioxide?
Photosynthesis uses light energy, carbon dioxide, and ______ to produce oxygen and sugar.
What is water?
When the sun shines on a plant, the leaves can make food from carbon dioxide and ________.
water
Identify the process

photosynthesis
Photosynthesis needs these four things to work.
What are sunlight, chlrophyll carbon dioxide, and water
