Transpiration and Environmental Factors

What environmental factors can affect the rate of transpiration in plants?

• Soil pH, precipitation, air pressure

• Altitude, soil type, plant species

• Cloud cover, soil moisture, CO2 concentration

• Temperature, humidity, wind, and light intensity

How does humidity influence transpiration in plants?

• High humidity increases transpiration in plants

• Humidity has no impact on transpiration in plants

• Transpiration rate is constant regardless of humidity levels

• Humidity affects transpiration rate by either slowing it down in high humidity or speeding it up in low humidity.

Explain the role of wind in the process of transpiration.

• Wind has no impact on transpiration as it is solely controlled by the plant's internal mechanisms.

• Wind enhances transpiration by facilitating the diffusion of water vapor from the leaf surface.

• Wind increases transpiration by decreasing the rate of water evaporation from the leaf surface.

• Wind reduces transpiration by blocking the stomata on the leaf surface.

Why does transpiration increase on a sunny day compared to a cloudy day?

• Higher temperatures on a sunny day increase evaporation from plant leaves.

• Plants conserve water by transpiring less on sunny days

• Increased cloud cover leads to more sunlight reaching the leaves

• Clouds trap heat, reducing the need for transpiration

Discuss the impact of temperature on transpiration rates in plants.

• Transpiration rates in plants are not affected by temperature

• Higher temperatures lead to decreased transpiration rates in plants

• Temperature directly affects transpiration rates in plants. Higher temperatures lead to increased transpiration rates, while lower temperatures result in decreased rates.

• Lower temperatures result in increased transpiration rates in plants
