What is needed for photosynthesis to occur? • Light is needed for photosynthesis to occur. • The plant’s chloroplasts use the light to make a sugar called glucose. Why do plants need glucose? • Glucose is the food for the plant. It gives the plant energy to grow. • Plants make enough glucose to be used during the night and on cloudy days when they don’t get sunlight. • The extra glucose is stored in the plant’s leaves and other parts as starch. Photosynthesis is a chemical reaction. Chemical reactions can be shown in the form of a chemical equation. EQUATION FOR PHOTOSYNTHESIS 6CO2 + ENERGY C6H12O6 + 6O2 CARBON DIOXIDE WATER GLUCOSE OXYGEN 6H2O + • The green pigment chlorophyll, which is in the chloroplasts captures light energy. • The light provides energy needed to change molecules of carbon dioxide & water into the sugar glucose. Why is this important to us? How does photosynthesis help us? • During the process of photosynthesis, oxygen is produced. The oxygen released is necessary for all living things. What is Cellular Respiration? The chemical breakdown of glucose molecules to release stored chemical energy. Takes place in the of all living things. Outer membrane Matrix Cristae Inner membrane • Release of energy from glucose using oxygen. • Takes place in the mitochondria.
