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
