Question

what will happen to the leave if under surface is covered with vaselive​

Answer 1

Answer:

$\huge\underline\mathtt\red{Answer:}$

Applying Vaseline on the surface of the leaf will result in the blockage of small pores(stomata) which are responsible mainly for respiration and thus cutting off the supply of Oxygen and Carbon Dioxide. In absence of respiration and photosynthesis , the plant leaf will die.

Answer 2

By applying Vaseline on leaves stomata gets covered and transpiration stops. This prevents loss of water vapour and the moisture of the leaf retain for sometimes. But as the layer of vaselin stops all type of gaseous exchange, both photosynthesis and respiration also cannot occur.
