Transpiration is the process by which water is lost from a plant through the stomata, or tiny pores, in the leaves. This process is essential for the plant's survival as it helps to regulate temperature, maintain turgidity, and transport nutrients and sugars throughout the plant. However, the rate of transpiration can be affected by a variety of factors, including environmental conditions, the plant's physiology, and the surrounding ecosystem. In this essay, we will explore some of the main factors that influence transpiration in plants.

One of the most important factors that affects transpiration is the humidity of the air. When the air is dry, the plant will lose more water through transpiration as it tries to maintain a balance between the water inside the plant and the water in the atmosphere. On the other hand, when the air is humid, the plant will lose less water through transpiration as the atmosphere is already saturated with water. This is why plants tend to transpire more on hot, dry days and less on cool, humid days.

Another factor that influences transpiration is the temperature of the air. As the air temperature increases, the rate of transpiration also increases. This is because the higher temperature causes the stomata to open wider, allowing more water to escape. On the other hand, when the air temperature is cooler, the stomata will remain closed, and the plant will transpire less.

The wind speed can also affect transpiration as it helps to remove the water vapor that has been released through the stomata. When the wind speed is high, it helps to remove the water vapor quickly, and the plant will transpire more. On the other hand, when the wind speed is low, the water vapor will remain around the plant for a longer period of time, and the plant will transpire less.

The surface area of the leaves also plays a role in transpiration as it determines the amount of water that can be lost through the stomata. Plants with large, flat leaves tend to transpire more as they have a larger surface area for the water to evaporate from. On the other hand, plants with small, narrow leaves will transpire less due to their smaller surface area.

Finally, the plant's physiology can also affect transpiration as different plant species have different types of stomata and different levels of transpiration. For example, some plants have stomata that are more sensitive to changes in humidity and temperature, while others have stomata that are less sensitive. Additionally, some plants have a thicker cuticle, or outer layer of the leaves, which helps to reduce the amount of water lost through transpiration.

In conclusion, there are many factors that can influence the rate of transpiration in plants, including the humidity and temperature of the air, the wind speed, the surface area of the leaves, and the plant's physiology. Understanding these factors can help us better understand how plants function and how to care for them.

These promotions may be governed by separate rules and regulations. Therefore, warmer air will increase the driving force for transpiration and cooler air will decrease the driving force for transpiration. In large plants, transpiration may be higher per plant, though on unit area basis, the rate of transpiration is more in the smaller plants than larger ones. The rate of water uptake by a plant, also known as the rate of transpiration, can be affected by multiple environmental factors. By participating in a promotion, you agree to be bound by the applicable rules and our decisions, which are final and binding in all matters related to the promotion. For example, plants from desert climates often have small leaves so that their small boundary layers will help cool the leaf with higher rates of transpiration.

In a Flowering plant, there is complicated traffic of materials heading on various paths, every organ getting a few substances and giving out a few different substances. However, plants can adapt to high humidity conditions by opening their stomata, or pores, to allow more water vapour to escape. This means that these leaves are aligned vertically in the direction of sunlight. Internet Cookies We use cookies on this website to provide you with better user experience. Light — Stomata are triggered to open in the light so that carbon dioxide is available for the light-dependent process of photosynthesis. Conversely, the entry of water into the guard cells opens the stoma.

This method is responsible for 60-90% of transpiration in plants. Some plants, such as the pineapple plant, do the opposite of what we expect: they keep their stomata open during the night and close them during the day! After permanent wilting the plant dies.

It occurs during midday for a brief period in almost all plants even when sufficient water is present in the soil. The epidermis of leaves and green stems have various stomata.

Availability of Water 7. Ans : During evaporation of water through the stomata of leaves, a pull is formed inside the xylem tissue that helps in the upward movement of water into the xylem vessels. The amount of water a plant can pull up is determined by the strength of the transpiration pull and the resistance to flow within the plant. Some significance of transpiration are: 1. It may sometimes be detrimental to the plant to lose this water via transpiration, but it is a necessary process.

When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.

Free trial We may offer free trials of our subscriptions at our discretion. Any decrease in atmospheric water produces a gradient for water to migrate from the leaf to the atmosphere. The latter is due to the fact that an extensive root system is more efficient in water uptake from soil. Summary Roots absorb a large amount of water from the soil, which is not required for plants. The rise in temperature causes an increase in the evaporation of water from the surface of leaves. Consequently, it will favor a rapid rate of transpiration.

Soil Water Where the supply of water from the soil is limited, the rate of transpiration tends to slow down. We will discuss everything on the transpiration process, factors affecting transpiration, the transpiration of plants, and more in this article.

Ans: Transpiration is defined as the process of loss of water in the form of water vapour from the aerial parts of the plant through the stomata, lenticels, and cuticles. Leaf Area Surface area to volume ratio; the more surface area exposed to the air, the more water vapour will be lost through transpiration.

At the point when any plant part goes through senescence, supplements might be removed from districts and moved to the developing parts. We shall only use your data for any purpose herein or as might be communicated to you at a later date with your express consent. Transpiration is the mechanism through which water vapour is lost via the stomata of plants. The midrib is the prominent vein that is present in the middle of the lamina. Very low levels of light at dawn can cause stomata to open so they can access carbon dioxide for photosynthesis as soon as the sun hits their leaves.

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.

Humidity ii Temperature The rate of transpiration increases with the increase in the temperature of the atmosphere as it is directly proportional to the temperature. But in monocots, as both sides of the leaf have an equal amount of stomata, so the rate of transpiration is equal on both the upper as well as lower surfaces of the leaf. It is the most important one. This pressure is called a transpiration pull.
