Question

Water absorption through roots can be increased by the keeping the plants

(a) in the shade

(b) in dim light

(c) under the fan

(d) covered with a polythene bag

Answer 1

(c) under the fan

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

Answer 2

(c) under the fan

Water absorption through roots can be increased by keeping the plants under the fan. Air movements carry away water vapour from leaves and this prevents air around them from becoming saturated with water vapour.
