Which of the following is a factor that affects the rate of transpiration?

Correct Answer: Humidity

Step 1: Understand what transpiration is. Transpiration is the process where plants lose water vapor from their leaves into the air.
Step 2: Learn about humidity. Humidity is the amount of water vapor present in the air.
Step 3: Recognize the relationship between humidity and transpiration. When humidity is low, the air has less water vapor.
Step 4: Realize that a greater difference (gradient) between the water vapor inside the leaf and the air outside causes more water to evaporate.
Step 5: Conclude that lower humidity increases the rate of transpiration because the water vapor moves from the leaf to the drier air more quickly.
