Question

What are the methods used by plants to get rid of excretory products?

Answer 1

Plants also excrete metabolic wastes products just like any other organism. 

Plants excrete the excretory products by the following process: 

i. Plants consume water for their life processes; however, they do not utilize it completely. The excess water is expelled through the process of transpiration. 

ii. 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. 

iii. CO₂ or gaseous wastes are eliminated through stomata. 

iv. 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

Answer 2

The main waste materials of plants are Oxygen , Carbon dioxide , water and other harmful substances . Oxygen is the waste product of photosynthesis and carbon dioxide is the waste product of respiration .

 • Plant gets rid of oxygen and  carbon dioxide and other gases through stomata present on leaves and lenticles present on stems .

• Access water is removed from the plant body through stomata by the process of 'Transpiration'.

• Metabolic waste products are stored in the leaves and the bark of the plants that gets removed whn leaves fall off .

• Other waste products like rubber , resin , gums are removed through bark . And some waste products are also removed into soil through roots.
