2.67a Excretion in plants

• Photosynthesis happens when a leaf absorbs light energy and in this process it combines CO2 with water to form glucose and oxygen which are given off as waste molecules.
• CO2 + H2O ---> C6H12oO6 + O2 -> Excretion
• Glucose and Oxygen happen through enzyme reactions, the glucose is broken down and forms ATP.
• Carbon dioxide is a metabolic waste and is excreted.
• C6H12oO6 + O2 ---> ATP + H2O + H2O -> Respiration
• Glucose molecule are broken down and energy is used to form ATP and get the waste of carbon dioxide and water to be given off.
• This waste process is called Excretion.
