Plants get rid of carbon dioxide and oxygen through diffusion. Old branches and leaves are shed off when they become useless. Plants release some waste products through roots also. Some waste products are deposited near bark as raisins or gums.

Plants excrete their wastes through transpiration or transportation. The waste in the plants are stored in the fruits, bark, leaves. When these are sent out of the plant then the wastes get excreted. The solid bodies are stored in the form of raphides.
