Evaporation and Transpiration

Transpiration and Evaporation are the two naturally occurring scientific processes in nature. Both the processes involve the formation of vapour with water as its main component. Though both the processes seem to be similar in their functioning and one can find difficulty in differentiating among the two but it should be noted that both the processes vary to a very much extent in their characteristics. To need to understand the difference between the two at first we need to be familiar with both the procedures and only then we will be able to understand the differentiation taking place in their functioning.  

Evaporation

The process of evaporation takes place around us in everyday lives and we will be familiar with it as we all might have noticed the process in our day-to-day lives. The process in which the water, present in the liquid form gets converted to the gaseous state is known as evaporation. The process involves solar energy as a heating body through which the water bodies get evaporated. The process usually involves the vapouring of the water every day from natural water bodies like seas, oceans, ponds, lakes, etc.

Apart from the water bodies the process also takes place in the bodies containing water in the moisture form such as soil and trees. The process is continuous but the rate of evaporation varies depending upon the season of the year. The process usually takes place at a higher rate in the summer season, comparatively lower in the winter season, and much lower in the rainy season.

 Factors Responsible for the Process of Evaporation

Temperature: Temperature is the foremost factor that involves in the process of evaporation. The more the temperature increases the higher the rate of evaporation.

Humidity: Humidity is the second factor in the process of evaporation. Humidity plays an exact opposite role to temperature in the process of evaporation. The higher the humidity the lower is the process of evaporation. Higher humidity results in lower temperatures leading to a decreased percentage of evaporation.

Wind: Wind also plays a major role in the process of evaporation. It carries the water droplets along with it thus resulting in the taking place of the process.

Transpiration

Unlike evaporation, the process of transpiration isn’t physically visible to us. It is a process that takes place inside the cell of the plants and hence can be termed a biological process. The process is not visible to the human eyes and thus cannot be detected happening of the process, unlike evaporation. Transpiration can be defined as the process in which the plants absorb the water and then remove the excess water through stomata. Even though it is a biological process, external factors present in nature play a major role in the taking place of the process.

Factors Responsible for the Process of Transpiration

Temperature: The process of transpiration takes place at a higher rate whenever there is an increased temperature in nature. The plants increate increased the percentage of water in the summer season when compared to the winter and rainy seasons. This is because the leaves start evaporating at a higher rate in the summer season than in the other seasons.

Light: Light plays a major role in the process of transpiration. The increased presence of light leads to increased and fastening of the process. This is mainly because the pores present on the leaves, also known as stomata detect the sunlight and conduct the process based on the amount of light present. It can also be noted the process of transpiration takes place only in the daylight and cannot be taken place at night in the absence of sunlight.

Soil: Soil also plays a major role in the conduction of the transpiration process. The process of transpiration involves the loss of water in access amount. Thus to make up for this loss the plants incur the water from the soil. Thus, if the soil does not have an adequate amount of water in it then the process of transpiration cannot be adequately taken place.

Conclusion

Transpiration and translocation are the processes that take place in the plant body. Both appear to be similar but have a significant difference that has been elaborated on in the above article. This article covers all aspects of transpiration, and evaporation, their importance, and the process of both signify the importance of each process in the plant body.
