Quick reviewQ. What is photosynthesis?A. Process where plants use sun’s energy to
make their own food
Q. What is the job of the chlorophyll?A. It absorbs or captures the sun’s energy
Q. What do animals and humans make that plants need?
A. Carbon Dioxide or CO2
Q. What do plants make for us that we need?A. Oxygen and food (Glucose) for energy
Q: What are the raw materials/ingredients for photosynthesis?
A: 6 Carbon Dioxide/CO2 molecules and 6 Water/H2O molecules
Q: What are the products of photosynthesis?A: 1 Glucose/C6H12O6 molecule and 6 Water/H2O molecules
Q: Why is the Sun’s energy over the arrow in the photosynthesis equation?A: Because the sun’s energy doesn’t change during photosynthesis
