Transpiration

The process of converting water into vapour through leaves in plant is called as_

• Photosynthesis

• Guttation

• Transpiration

• Osmosis

External factors of transpiration:

• Intensity of Sunlight

• Loss of Leaves

• Narrow Leaves

• Humidity

Which of the following is NOT a factor that affects the rate of transpiration?

• sunlight

• humidity

• wind speed

• rain

An apparatus used to measure the rate of transpiration

• Garreau's potometer

• Darwin's potometer

• Ganong's potometer

the atmospheric humidity in farm A is 35%, while that in in farm B is 45%. Which of the following statements is true

• Farm B will experience a higher rate of transpiration because of the higher water vapour gradient across the leaf surface
• Farm A plants will experience higher rate of transpiration because of the higher water vapor gradient across the plant leaves
• Farm B will experience higher rate of transpiration because more of the stomata there will be open
• Farm A will experience lowerer rate of transpiration because of the reduced thickness of the plants' waxy cuticle

Water molecules pull each other up the xylem due to ______________.

• capillary action

• root pressure

• osmosis

• active transport
