The waste products of a plant are carbon dioxide, water vapour and oxygen.

Plants produce several waste products, including:

• Organic by-products:These include gums, oils, latex, and resins, which plants store in their barks, stems, and leaves

• Carbon dioxide: A waste product of respiration, which plants exhale through stomata in their leaves 

• Water vapour: A waste product of respiration, which plants exhale through stomata in their leaves and the surfaces of their fruits and stems 

• Oxygen:A waste product of photosynthesis, which plants exhale through stomata in their leaves
