Why circulation and transpiration system is required in the body?

Dear Student.
Please find below the solution to the asked query.
 
Higher organisms like mammals and birds need high amount of energy for their metabolic processes. Circulation transports oxygen and food to all parts of the body which enables production of sufficient energy for the organism.
 

Following are the advantages of transpiration to plants:

• It creates transpirational pull for transport.

• It supplies water for photosynthesis.

• It transports minerals from soil to all parts of a plant.

• It cools the surface of the leaves (due to the evaporation of water).

• It keeps the cells turgid; hence, maintains their shape.
