Answer 1

$\textbf{ii}$

This is because, their transpiration will occur, and thus it will pull up water from the roots.

Answer 2

Water absorption through the roots can be enhanced by keeping the plants under the fan.

As by keeping the plants under the fan the transpiration process is boosted. Therefore, more amount of water and other minerals are absorbed by the plant roots from the soil.

The more is the rate of evaporation of water from the plants the greater is the rate of transpiration.
