2.67 Excretion in plants and Humans

• Plants-
• Excretion-
• Uses Photosynthesis 
• Takes light energy, CO2 and water and turns it into Glucose
• (Light + Carbon Dioxide + Water -> Glucose + Oxygen)
• Oxygen becomes the waist product from this process 
• Aerobic Respiration-
• Glucose + Oxygen -> CO2 + Water + ATP
• Uses enzyme to convert Glucose and Oxygen to CO2, Water & ATP
• Water and CO2 Get's excreted 

• Humans-
• Lungs-
• Takes in Oxygen, excretes Carbon Dioxide
• Kidneys-
