The process of photosynthesis.
The most important chemical reaction on our planet.
Equation for the Chemical Reaction of Photosynthesis (symbol)
6CO2 + 6H2O ->C6H12O6 + 6O2
Equation for the Chemical Reaction of Photosynthesis (words)
Carbon Dioxide + Water -> Glucose + Oxygen
Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.
Equation for the Chemical Reaction of Photosynthesis
The process of changing light energy to chemical energy.
Occurs in plants and some algae .
Plants need light energy, CO2, and H2O .
Takes place in the chloroplasts, using chlorophyll.
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 released in this reaction.
Carbon dioxide enters the leaf through holes called stomata.
CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose.
The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants.
Some of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissue
We cannot make our own food (glucose, energy), we must get our food from plants.
Importance of Photosynthesis to Humans
The first step in the food chain.
Released during photosynthesis; is necessary for all living things.
The release of chemical energy for use by cells.
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.
The breakdown of glucose molecules to release energy.
Takes place in all living things.
Is a step by step process.
Chemical equation for cellular respiration. (words)
Glucose + Oxygen -> Carbon Dioxide + Water
Chemical equation for cellular respiration. (symbol)
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
Glucose to ATP.
