What is the total loss of water from the soil via evaporation and transpiration by plants?
The total loss of water from the soil via evaporation and transpiration by plants is referred to as evapotranspiration . The concept of evapotranspiration is vital in relation to agriculture. It is because if evapotranspiration rates can be predicted in ahead, one can ascertain how much irrigation is required for crops.
How do stomata make up for water loss?
They make up for the loss of water by drawing water from the soil. Thus, if the soil does not contain adequate water, the stomata will close to preserve water leading to less photosynthesis. The main differences between evaporation and transpiration have been illustrated in the table below.
What happens when the temperature of the leaves is high?
Temperature – When the temperature is high, plants transpire more as water on the surface of leaves starts evaporating more quickly with increasing temperature . Light – The stomata or tiny pores present in leaves detect presence and absence of light. The stomata open up widely when there is enough light, which facilitates both transpiration ...

Evaporation is a continuous process; however, the rate of evaporation at a given time can vary based on several factors. These factors are as follows –. Temperature – High-temperature results in increasing rate of evaporation and vice versa. Humidity – High level of humidity means that the atmosphere already contains a significant amount ...
How does wind affect evaporation?
Wind – Wind help in evaporation by carrying away water vapour, which helps in the formation of more water vapour. Hence, wind speed also affects the rate of evaporation.
Evaporation vs Transpiration
The main difference between Evaporation and Transpiration is Evaporation takes place on any surface, such as on the floor or beach, etc. whereas Transpiration is a process that occurs in the plant cell only. Other than this also both of them are very different on the basis of occurrence, speed, and many more.
What is Evaporation?
It is a process of water/liquid turning into a gaseous form in the presence of sunlight. The factors that affect Evaporation are:
What is Transpiration?
It is a process of water evaporating from the plants into thin air or atmosphere. The various types of Transpiration are:
Main Differences Between Evaporation and Transpiration
Evaporation is a process that can take place on any surface, whereas Transpiration only takes place in plants, i.e., in plant cells. This means that in Evaporation, water is lost from the surface, but in Transpiration, water is lost from plant cells.
Conclusion
Both the Evaporation and Transpiration processes are associated with the water. Both of them link the terrestrial and atmospheric hydrological processes and are important factors of the hydrological cycle. Both of them have a similarity of water turning from liquid (from the surface) to gaseous form, i.e., water vapors.
Evaporation Vs. Perspiration
While Evaporation may occur on any surface, such as a floor or a beach, etc., Transpiration only takes place inside a plant’s cellular structure. Both of them are highly distinct in terms of how often they occur, how fast they move, and a host of other factors.
What is Evaporation?
In the presence of sunshine, water/liquid changes state and becomes gaseous. Evaporation is affected by the following factors:
What is Transpiration?
As the water evaporates from the plants, it is dispersed into the atmosphere as a fine mist. Different kinds of Transpiration include:
Difference Between Evaporation and Transpiration
In contrast to Evaporation, which may occur on any surface, Transpiration can only occur inside the cells of living plants. As a result, while water is lost from the surface by Evaporation, it is lost from the cells of plants via Transpiration.
Conclusion
The water contains both Evaporation and Transpiration processes. The hydrological cycle is made up of both terrestrial and atmospheric processes, and both of them are key components of this cycle. There is some resemblance between the two in terms of water vapor transforming from liquid to gaseous state.
How does transpiration work?
Transpiration is the physiological process of the release of water from plants through small openings in their leaves or stomata. Plants can control the loss of water by opening and close the stomata which also help them survive in hot summer weather. Water changes into vapors and is released into the atmosphere.
What happens to transpiration rate when humidity rises?
When relative humidity of the air rises the transpiration rate decreases. It is easier for water to evaporate into the dry air than into more saturated air. Similarly, increased movement of the air around the plant or wind will result in a higher transpiration rate.
What is the physiological process of loss of water from living surfaces?
Transpiration is the physiological process of loss of water from living surfaces while evaporation is the loss of water from any surfaces.
What happens when liquid evaporates?
Evaporation occurs when the surface of the liquid is exposed and allows molecules to escape and form water vapors. These vapors then make clouds. Different factors affect the evaporation process. If the air already has a high concentration of the substance evaporating, then substance will evaporate more slowly.
What is the process of losing water in plants?
It also includes a process in which loss of water occurs in liquid form the leaves and stem of the plants; this process is called guttation. Several studies have found that 10% of the atmospheric moisture is the result of transpiration by the plants while remaining 90% results in evaporation from oceans, seas, and other water bodies.
What is the process of releasing water into the air called?
The process of releasing water into the air through both transpiration and evaporation is called evapotranspiration. Transpiration is a physiological process of water loss from the plants to the air while evaporation is a physical process of water loss from the surface to the air. Transpiration is present in plants naturally while evaporation ...
What are the forces that affect the evaporation process?
Intermolecular forces also affect evaporation process rate. The stronger these forces keeping the molecules together in the liquid state, the more energy one must get to escape. Similarly, pressure, surface area and temperature of the substance also affect evaporation rate. ADVERTISEMENT. CONTINUE READING BELOW.
What Is Transpiration?
Transpiration is the process by which plants lose water in the form of vapor to the atmosphere through the stomata. Transpiration cools the plant, changes osmotic pressure of cells and enables mass flow of mineral nutrients and water from roots to shoots.
What Is Evaporation?
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gaseous state due to an increase in temperature and/or pressure. In evaporation, the particles at the surface gain enough energy to overcome the forces of attraction and convert themselves into vapors.
How does transpiration help the plant?
Transpiration is controlled by osmotic potential and water potential. Transpiration makes the surface of leaves and young stems wet and protects them from sunburn. Evaporation provides dryness to the free surface.
What is transpiration regulated by?
Occurs during the daytime. It is regulated by temperature, light, concentration, pH, hormones and carbon dioxide. There is no such regulations or control over the Evaporation. It helps in the uptake of minerals and nutrients. Transpiration is controlled by osmotic potential and water potential.
What are the two types of natural processes that occur in the atmosphere?
Evaporation and transpiration are the two different types of naturally occurring process in the atmosphere. They are essential components of the hydrological cycle and play an important role in linking the terrestrial and atmospheric hydrological processes. In both the process, water is evaporated from the surface to the atmosphere in the form ...
How does the stomata help in transpiration?
Along with the exchange of gases, stomata also helps in transpiration by actively opening and closing of their tiny pores for the movement of water molecules from their interior parts of the plants to the atmosphere in the form of vapours.
How much energy is needed to evaporate water?
Altogether, the total amount of energy required for the evaporation of one gram of water is about 600 calories of heat energy.
What is the process of water being lost in the form of water vapours?
Transpiration is a biological process in which the water molecules are lost in the form of water vapours from the aerial parts of the plants. This natural phenomenon is carried in all green plants and specifically take place in a tiny opening called as stomata.
What is the process of transforming water into a gaseous state?
The natural process of transforming water from its liquid state to the gaseous state is mainly referred to as evaporation. This natural phenomenon generally takes place only when water is available- it can be from any water bodies including oceans, rivers, lakes, ponds, or even from the soil.
