Plants do eliminate some wastes but instead of eliminating to the exterior like animals do they secrete their metabolic wastes into their nonliving tissues or cavities within the plant. Plant cells have internal sacs called vacuoles that are used for storage including waste storage. So with plants is is called secretion rather than excretion for their nongaseous byproducts. The primary plant waste is oxygen and it is released as a gas through leaf stomata and stem lenticles. Beyond this they also secrete from 10 to 25% of their total carbohydrate product via their roots and the soil to attract symbiotic soil organisms. This is their root carbohydrate exudate.

Trees use the heart wood. As a tree matures the sapwood ages and becomes the heartwood with the addition of tannins and metabolic waste materials from the tree.

Some botanists propose that leaves may also be repositories of annual wastes by trees. Plants have found ways of using these toxins to ward off herbivorous pests by depositing secondary metabolites in leaves to make them unpalatable or harmful. They may also secrete them in the soil to prevent other plants from growing nearby.

LOL yes actually tress and plants do poo. When trees/ plants use the "food" they've collected and made from photosynthesis their waste is then brought down through the xylem, feeding the roots, helping the roots to grow as well. Intresting huh?!

yes -- it's called Oxygen. their poop is the good stuff that we breathe -- just like animal poop makes great fertilizer for plants!
