10th - Biology - Transpiration

Most transpiration in herbaceous plant occurs through:

• Stomata

• Lenthicels

• Cuticle

• Hydathodes

On a dry, Sunny day, how does water vapour move through the stomata of a leaf?

• Into the leaf by diffusion

• Into the leaf by respiration

• Out of the leaf by diffusion

• Out of the leaf by respiration

Transpiration is highest during:

• Rainy season

• Winter

• Summer

• Autumn

Which of the follwing does not affect the rate of transpiration?

• Light

• Humidity

• Wind

• Age of the plant

The rate of transpiration of the increase with:

• Increase in humidity

• Increase in wind velocity

• Reduced light intensity

Transpiration is the evaporative loss of water from .............................. .

• Roots

• Leaves

• Stem

• Both Leaves and Stem
