Transpiration is the process by which water is evaporated from the leaves of plants. It is an important process that helps to regulate the temperature of the plant and prevent it from overheating, as well as providing the plant with the water it needs to grow and survive. There are several factors that can affect the rate of transpiration in plants, including humidity, temperature, wind, and light.

One of the main factors that affects transpiration is humidity. When the air is humid, there is already a high amount of water vapor present, which means that there is less room for water to evaporate from the leaves of the plant. As a result, the rate of transpiration will be slower in humid conditions. On the other hand, when the air is dry, there is more room for water vapor to evaporate, and the rate of transpiration will be faster.

Temperature is another important factor that affects transpiration. In general, the higher the temperature, the faster the rate of transpiration. This is because heat increases the energy of the water molecules, which makes them more likely to escape from the plant's leaves as vapor. However, if the temperature becomes too high, it can actually inhibit transpiration by damaging the plant's cells and disrupting the movement of water through the plant.

Wind is another factor that can affect transpiration. When the wind is blowing, it helps to remove the water vapor that has evaporated from the plant's leaves, which can increase the rate of transpiration. On the other hand, if the wind is calm, there is less movement of air, and the rate of transpiration will be slower.

Light is also a factor that can affect transpiration. In general, the more light a plant receives, the faster the rate of transpiration. This is because light provides the energy needed for the plant to carry out photosynthesis, which in turn increases the demand for water. However, if a plant receives too much light, it can become stressed, which can inhibit transpiration.

In conclusion, there are several factors that can affect the rate of transpiration in plants, including humidity, temperature, wind, and light. Understanding these factors can help us to better understand how plants respond to their environment and how to care for them in different conditions.

Transpiration & Factors affecting transpiration

The water potential gradient is the difference in water potential between the inside of a cell and the outside environment—a higher water potential gradient results in a higher rate of transpiration. Plants also transpire through lenticels, which are small gaps in their bark. The slower the rate of transpiration, the bigger the boundary layer. Our membership accounts are billed monthly or annually and do not automatically renew after the period. Low RH also favors faster transpiration due to stronger atmospheric demand. When there is less water available for the plants, dehydrated mesophyll cells produce the plant hormone abscisic acid, which forces the stomatal pores to shut and reduces water loss during oxygen release and carbon dioxide absorption. At higher temperatures, the stomata of the leaves close to prevent further water loss, reducing the transpiration rate.

While we make every effort to ensure the accuracy and reliability of our services, we cannot guarantee that they will be error-free or uninterrupted. The symptoms of wilting are not shown by thick-walled tissues. At 50% RH, the water potential gradient is more steeper 93. Conclusion The rate of transpiration is affected by two variables first is internal such as, Surface Area of the Leaf, Stomata and Boundary Layer and the second one is external factor i. On the other hand, leaves those possesses thick cuticle, thick cell walls, well-developed palisade parenchyma, Sunken stomata etc. Similarly, the waiver of a breach of these terms and conditions shall not constitute a waiver of any subsequent breach.

In the event of a conflict between the promotion rules and these terms and conditions, the promotion rules will take precedence. How are the various abiotic factors may affect plants? When tissue is dry, it will absorb water from the surrounding air more readily, leading to increased transpiration. I make a lot of the resources from scratch because I have a particular style to the layout of my points and really try to make my powerpoints engaging to the eye and for the lessons to have a clear structure. Internal or Structural or Plant Factors Internal factors include the structural factors of the plant that affect the rate of transpiration which are as follows: i Leaf Surface Area The rate of transpiration is faster if the surface area of the leaf is more. This condition usually occurs during drought or when the soil is frozen or at such a low temperature that roots are unable to absorb water. We will give you reasonable notice of any fee changes so you have the opportunity to cancel your subscription before the changes take effect.

Promotions refer to contests, sweepstakes or other promotions offered by us through the website. What are the two types of factors affecting transpiration? But the rate of transpiration per unit surface area is more in smaller leaves than in larger leaves because of the higher number of stomata in smaller leaves. ADVERTISEMENTS: The movement of the air increases the rate of transpiration by removing the saturated air around the leaves. We also keep a track of the devices you use from time to time. Relative Humidity This environmental factor affects transpiration by regulating stomatal movement and atmospheric demand.

Despite these drawbacks, it is vital. Temporary wilting is corrected only after the rate of transpiration decreases in the afternoon accompanied by replenishment of water around the root hairs. The Effect of Wind on Transpiration The faster the wind speed, the greater the transpiration rate if all other conditions are constant.

The stomata are typically open during the daytime, allowing the entry of CO2 and the exit of O2. If you do not agree with or you are not comfortable with any aspect of this Privacy Policy, you should immediately discontinue access or use of the site and our Services. Because most of the transpiration occurs through stomata, the rate of transpiration is quite high in light. The right to ask us to transfer your data to another organisation, or you, in certain circumstances. The transpiration rate will be faster at 50% than at 90% RH. In some cases, at the point of payment, you are transferred to a secure page on the website or some other reputable payment service provider. To maintain a constant water balance, plants must increase their transpiration rate.
