Question

1. How will the following conditions affect
transpiration ?
(i) Still air (ii) Midday high temperature
(iii) Dry air (iv) Dim sunlight
(v) Insufficient absorption of water by the
roots
​

Answer 1

$\huge{\underline{\underline{\star{\mathfrak{\red{Answer}{\star}}}}}}$

$\sf{Dim\:Sunlight}$

$\mathfrak{Reason}$

This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. Dim sunlight leads to fall of transpiration, thus water does not evaporates.
