Do plants eliminate of waste products?

Plants also eliminate waste products, although not in the same way as animals. Plants eliminate waste products through their leaves, stems, and roots. The process of elimination of waste products is called guttation. Guttation occurs when water vapor condenses on the surface of the plant and forms droplets. These droplets contain waste products such as salts and minerals. Guttation is most common in the morning, when the air is cool and humid.
