What Happens During Photosynthesis? Ingredients needed: – Water (H 2 O) – Sunlight – Carbon Dioxide (CO 2 ) Stage one: 1.Plants absorb energy from the sun by their CHLOROPLASTS (found in the leaves) 2.CHLOROPHYLL converts the light energy and splits water into energy (hydrogen) and oxygen 3.Oxygen is given off into the air

What Happens During Photosynthesis? Stage Two:

What Happens During Photosynthesis? Stage Two: 1.Cells produce sugars (glucose) by using the CO 2 and hydrogen Photosynthesis Equation
