What will happen if :

(a)

Xylem tissue in a plant is removed ?

(b)

We are injured and start bleeding ?

(a) Movement of water and minerals from the soil to other parts of the plant will stop and it will ultimately die.

(b) Platelet cells plug these leaks by helping the blood to clot at these points of injury. / Leakage of blood would lead to loss of pressure which would reduce efficiency of pumping system.
