What is Photosynthesis?The process of photosynthesis is a chemical reaction.

It is the most important chemical reaction on our planet.What is the Equation for the Chemical Reaction of Photosynthesis?What is the equation for the chemical reaction of photosynthesis?

What is the equation for the chemical reaction of photosynthesis?

Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.Describe PhotosynthesisDescribe PhotosynthesisThe process of changing light energy to chemical energy Energy stored as sugarOccurs in plants and some algae Plants need light energy, CO2, and H2O Takes place in the chloroplasts, using chlorophyll, the green pigment in plantsWhat happens during photosynthesis?What happens during photosynthesis?Plants capture light energy and use that energy to make glucose

Sunlight provides the energy needed by chlorophyll to change molecules of carbon dioxide and water into glucose

Oxygen is also released in this reactionWhat happens during photosynthesis?Carbon dioxide enters the leaf through holes called stomata CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucoseThe sugar is moved through tubes in the leaf to the roots, stems and fruits of the plantsSome of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissueWhy is this important to us?Why is this important to us?We cannot make our own food (glucose, energy), we must get our food from plants.Plants are the first step in the food chain.Why is this important to us?The oxygen released during photosynthesis is necessary for all living things.Learn more about photosynthesis at:http://www.ftexploring.com/me/photosyn1.html What is Cellular Respiration?What is Cellular Respiration?The release of chemical energy for use by cells.What is Cellular Respiration?Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a a form that can be used by the organism.

This process is cellular respiration.Describe Cellular RespirationDescribe Cellular RespirationThe breakdown of glucose molecules to release energy

Takes place in all living things

Is a step by step processWhat is the chemical equation for cellular respiration?What is the chemical equation for cellular respiration?
