Transpiration

Which part of the plant primarily facilitates transpiration?

• Roots

• Flowers

• Stem

• Leaves

What is the primary process through which plants lose excess water?

• Condensation

• Photosynthesis

• Transpiration

• Respiration

What creates the suction force that helps in the upward movement of water in plants?

• Capillary action

• Transpiration pull

• Gravity pull

• Photosynthesis pull

What is the main force that pulls water and minerals up the plant?

• Magnetic pull

• Gravitational force

• Transpiration pull

• Electrostatic force

Which factor does NOT directly affect the rate of transpiration?

• Wind

• Temperature

• Humidity

• Soil type

How does humidity affect the rate of transpiration?

• Lower humidity increases the rate

• Humidity has no effect on transpiration

• Higher humidity increases the rate

• Only extreme humidity affects transpiration

What effect does temperature have on transpiration?

• Higher temperature decreases the rate

• Higher temperature increases the rate

• Temperature has no effect

• Lower temperature increases the rate

What happens to the stomata on windy days?

• They close

• They enlarge

• No change

• They multiply

How does wind speed affect transpiration?

• Stronger wind increases the rate, up to a point

• Wind speed inversely affects the rate

• Stronger wind decreases the rate

• No effect

How does light intensity affect transpiration?

• Bright light increases the rate

• Bright light decreases the rate

• Only UV light affects the rate

• No effect
