What are the methods used by plants to get rid of excretory products?
Excretion is process where all waste material and the excess amount of water, minerals and salts are excreted out through the life processes which are involved by the plants as well as by the animals. In plants various methods are used to get rid of excretory products.
-
Through stomata:- when the process photosynthesis occurs, in which plants make their food by their own with the help of sun’s energy. This process releases oxygen by consuming carbon dioxide from the environment and also releases their end products in the environment through the stomata, therefore it helps in the exchange of gases.
-
Through evaporation or transpiration:- the amount of water, minerals and salts are excreted out through stomata.
-
Some other waste removed with the dead cells when plant loses some of their leaves or some waste are stored in the vacuoles which are resins and gums are excreted out.
-
Wastes products as resins and gums are present in the old part of the xylem which are also get excreted.
-
Some wastes product can be excreted into the soil or through petals, fruits etc.
