Photosynthesis Grade 7 Science
What is photosynthesis? • Process plants use to make their own food • Some plants cells contain chlorophyll • Chlorophyll (green color) makes photosynthesis possible • It occurs in the chloroplast
The sunlight is combined with water, Carbon Dioxide and nutrients from the soil. CO2
6CO2 + 12H2O + light energy C6H12O6 + 6O2 The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen. Sugar + Air O2
Equation for Photosynthesis 6CO2 + 6H2O + Sunlight C6H12O6 + 6O2 Reactants Products
Reactants Reactants are what you start with in a chemical reaction. These are the substances that enter into a chemical reaction.
Products • Products are what you end with in a chemical reaction. • Products are substances which form as a result of a chemical reaction.
Animals including humans make the CO2 (carbon dioxide) plants need.They (the plants) make the O2 (oxygen) and food we need.
Cellular Respiration • The process by which cells use oxygen to produce energy from food. • It occurs inside the Mitochondria
Cellular RespirationEquation C6H12O6 + 6O2 6CO2 +6H2O + Energy (ATP) Reactants Products
