What are the factors affecting transpiration in plants?
Understand the Problem
The question pertains to the concept of transpiration in plants, specifically how different factors affect the rate of transpiration. It includes steps for conducting an experiment to study these effects.
Answer
Light, air movement, temperature increase; humidity decreases transpiration.
Factors affecting transpiration include light intensity, air movement, humidity, and temperature. Increased light intensity, air movement, and temperature increase transpiration, while increased humidity decreases it.
Answer for screen readers
Factors affecting transpiration include light intensity, air movement, humidity, and temperature. Increased light intensity, air movement, and temperature increase transpiration, while increased humidity decreases it.
More Information
Transpiration is the process by which water is absorbed by roots and evaporated from plant leaves. Higher temperatures provide energy for evaporation, increased light opens stomata, and air movement removes moist air. Humidity reduces the water concentration gradient, slowing evaporation.
Tips
A common mistake is assuming that all factors affect transpiration in the same way. Always consider the role of each factor in the evaporation process.
