Plants also excrete metabolic waste products just like any other organism. Plants excrete the excretory products by the following process:
- Plants consume water for their life processes, however, they do not utilize it completely. The excess water is expelled through the process of transpiration.
- Other excretory wastes get accumulated in the cell vacuoles, eventually forming resin and gum. This is usually observed in old xylem tissues. Some of these wastes are stored in the leaves which later droop and wither away.
- Carbon dioxide or gaseous wastes are eliminated through stomata.
- Some other forms of wastes can be excreted into the soil. Excretory products can also be stored as oils and latex in the barks of trees.
