Why is transpiration important for plants?
Transpiration occurs in plants during the day time when temperature is high. It is basically the loss of water from plants through minute openings plants posses like stomata, cuticular openings, trichomes etc.
● Transpiration helps in maintaining the basic thermostasis of plants which is important the metabolic processes to occur naturally.
● Also, it creates the negative pressure gradient, which is responsible for absorbing water and minerals from the soil with the help of cohesive and adhesive forces.
