Transpiration pull will be maximum under which set of the following conditions?

Open stomach, dry atmosphere and moist soil. (b) Open stomata, high humid atmosphere and well irrigated soil. (c) Open stomata, high humid atmosphere and dry soil. (d) closed stomata, dry atmosphere and dry soil.

With decrease in atmospheric pressure, the rate of transpiration will

increase (b) decrease rapidly (c) decrease slowly (d) remain the same

The rate of transpiration is more when (a) atmosphere is dry (b) temperature is high (c) humidity is high (d) atmosphere is dry and temperature is high

One of the internal factors which affect the rate of transpiration is (a) big size of the leaf (b) colour of the leaf (c) sunken stomata (d) sunny day

Guttation takes place through (a) stomata (b) lenticels (c) lower epidermis of leaves (d) hydathodes

The loss of water as water vapour from the acrial parts of a plant is known as (a) evaporation (b) perspiration (c) guttation (d) transpiration

Transpiration will be fastest when the day is (a) cool, humid and windy (b) hot, humid and still (c) hot, humid and windy (d) hot, dry and windy

Most of the transpiration in tall trees occurs through (a) stomata (b) Lenticels (c) cuticle (d) Bark

Transpiration is best defined as (a) loss of water by the plant (b) evaporation of water from the surfaces of a plant (c) loss of water, as water vapour, by a plant (d) release of water by a plant into the atmosphere
