Lenticular transpiration This type of transpiration is the loss of water from plants as vapor through the lenticels. The lenticels are tiny openings that protrude from the barks in woody stems and twigs as well as in other plant organs.
What is the difference between transpiration and lenticular transpiration?
Transpiration involves mainly the xylem cells which become active during absorption process by the roots. *Lenticular transpiration is the type of transpiration which occurs through the small pores called as lenticels present in the bark.
How much water is lost by lenticular transpiration in plants?
Huber observed in some plants that water lost by lenticular transpiration was about 0.1% of the total transpiration loss. He further noted that coating the bark of the trees reduced the total loss by 20% from total bark surface, showing that some water loss was taking place through general surface of the bark also.
What type of transpiration is cuticular transpiration?
Cuticular Transpiration. Cuticular transpiration is the evaporation of water from a plant’s cuticle. The cuticle is a waxy film that covers the surface of a plant’s leaves. This form of transpiration does not account for much of a plant’s water loss; about 5-10 percent of the leaves’ water is lost through the cuticle.
What does transpiration mean in biology?
Transpiration Definition Transpiration is the evaporation of water from plants. Most of the water absorbed by the roots of a plant —as much as 99.5 percent—is not used for growth or metabolism; it is excess water, and it leaves the plant through transpiration.
What is a lenticular transpiration?
Lenticular transpiration is the evaporation of water from a plant's lenticels. When compared to stomatal transpiration, the amount of water lost in this manner is negligible, although it can increase in a dry environment, exactly like cuticular transpiration.
What are examples of lenticular transpiration?
Lenticels are the pig openings, lens-shaped in thick stems of angiosperm trees. They are kind of large stomata. Through these pores, water can also exit in the form of water vapours. Thus it is called lenticular transpiration.
What is lenticular transpiration mention one major difference?
Transpiration occurring through lenticels i.e. minute openings on the surface of old stems is called lenticular transpiration. Stomatal transpiration is controlled by the plant by altering the size of the stoma where as this does not happen in case of lenticular transpiration.
Where does lenticular transpiration occur?
So, the correct answer is 'Woody stem'.
What is lenticular transpiration class 10th?
Loss of water that takes place through lenticels which are small minute pores present on the stem of many woody plants is called lenticular transpiration.
What are the 4 types of transpiration?
Depending upon the plant surface transpiration is of the following four types:Stomatal Transpiration:Cuticular Transpiration:Lenticular or Lenticellate Transpiration:Bark Transpiration.
What is the difference between lenticular and stomatal transpiration?
Difference between lenticular and stomatal transpiration Loss of water from plants as vapor through the lenticels is called lenticular transpiration. Loss of water from plants as vapor through the stomata is called stomatal transpiration.
What is the major difference between lenticular transpiration and stomatal transpiration?
LenticularStomatalLenticels are special opening that develops on the barks of the older stem in place of stomata.The amount of transpiration from lenticels certainly more than the cuticular transpiration, but very much less than the stomatal transpiration.
What is the percentage of lenticular transpiration?
0.1%Cuticular transpiration accounts for 5-10 % whereas, lenticular transpiration accounts for 0.1% of the total transpiration.
What are the 3 types of transpiration?
There are the following different types of transpiration in plants: Stomatal transpiration. Lenticular transpiration. Cuticular transpiration.
What is lenticular biology?
Lenticular. 1. (Science: anatomy) Pertaining to or shaped like a lens. 2. (Science: ophthalmology) Pertaining to the crystalline lens of the eye.
Why is lenticular transpiration less than stomatal transpiration?
Stomatal transpiration occurs through stomata while lenticular transpiration occurs through lenticels and cuticular transpiration occurs through cuticles. Thus, this is the key difference between stomatal lenticular and cuticular transpiration.

There are the following different types of transpiration in plants: Stomatal transpiration. Lenticular transpiration. Cuticular transpiration.
What is the difference between lenticular and stomatal transpiration?
Difference between lenticular and stomatal transpiration Loss of water from plants as vapor through the lenticels is called lenticular transpiration. Loss of water from plants as vapor through the stomata is called stomatal transpiration.
How many types of transpiration are there?
The three major types of transpiration are: (1) Stomatal Transpiration (2) Lenticular Transpiration and (3) Cuticular Transpiration.
What is stomatal cuticular and lenticular transpiration?
Stomatal transpiration is the evaporation of water through stomata while lenticular transpiration is the evaporation of water through lenticels and cuticular transpiration is the evaporation of water through cuticles. So, this is the key difference between stomatal lenticular and cuticular transpiration.
How much water is lost by lenticular transpiration?
Huber observed in some plants that water lost by lenticular transpiration was about 0.1% of the total transpiration loss. He further noted that coating the bark of the trees reduced the total loss by 20% from total bark surface, showing that some water loss was taking place through general surface of the bark also.
Where does transpiration take place?
Transpiration mainly takes place through surface of leaves. It is known as Foliar transpiration (more than 90%). Transpiration occurs through young or mature stem is called as Cauline transpiration.
What is the term for water that evaporates through the stems?
Lenticular Transpiration: Sometimes water may evaporate through certain other openings present on the older stems. These openings are called Lenticels and the transpiration that takes place through term is known as Lenticular Transpiration.
What is the name of the process where water evaporates from a plant?
Water vapour diffuses out through minute pore (stomata) present in soft aerial part of plant is known as Stomatal Transpiration. Of the total water loosed, near about 85 – 90% of water loosed by the stomatal transpiration. Type # 2. Lenticular Transpiration: Sometimes water may evaporate through certain other openings present on the older stems.
How much water does a plant lose through the cuticle?
Loss of water may also take place through cuticle, but the amount so lost is relatively small and make up only about 5 to 10 percent of the total transpiration . This type of transpiration depends upon the thickness of the cuticle and presence or absence of wax coating on the surface of the leaves. Xerophytic plants generally have very thick cuticle and wax coating on the leaves and stem in order to check cuticular transpiration.
How does transpiration occur?
First, water transpires from plants and enters the atmosphere as water vapor. Water from Earth’s oceans, lakes, and rivers also evaporates into the atmosphere. The evaporation from Earth’s waterways and from plants via transpiration is collectively known as evapotranspiration. In the atmosphere, the water forms clouds, and then it falls back to earth again as rain or snow. Precipitation collects again in earth’s waterways, or it goes into the soil, where it enables plants to grow. Then water evaporates from plants, oceans, lakes, and rivers again, completing the cycle.
Why is transpiration important?
Transpiration is very important for maintaining moisture conditions in the environment. As much as 10 percent of the moisture in the Earth’s atmosphere is from transpiration of water by plants.
What is the evaporation of water from the lenticels of a plant?
Lenticular Transpiration. Lenticular transpiration is the evaporation of water from the lenticels of a plant. Lenticels are small openings in the bark of branches and twigs. Not all plants have lenticels. The amount of water lost this way is very small compared to stomatal transpiration , but as with cuticular transpiration, ...
How does temperature affect transpiration?
There are many factors that affect transpiration. One such factor is temperature. When temperatures increase, the stomata of leaves open and more water transpires. Plants that grow in warmer climates transpire more. Moisture levels of the air and soil are other important factors. When relative humidity of the air increases, there is more moisture in the air, so transpiration decreases. However, if there is more moisture in the soil, plants will transpire more because they are taking in more water. More wind also increases the rate of transpiration because it decreases the relative humidity around a plant. Of course, some plants also just transpire more than others. Plants that live in dry environments, such as cacti, have evolved to conserve water in part by transpiring less water. This allows them to thrive in arid regions like the desert.
Why do plants transpire more when there is more moisture in the soil?
However, if there is more moisture in the soil, plants will transpire more because they are taking in more water.
What is the process of evaporating water from a plant's cuticle?
Cuticular Transpiration. Cuti cular transpiration is the evaporation of water from a plant’s cuticle. The cuticle is a waxy film that covers the surface of a plant’s leaves. This form of transpiration does not account for much of a plant’s water loss; about 5-10 percent of the leaves’ water is lost through the cuticle.
How does transpiration affect the ecosystem?
Transpiration has side effects for other organisms in an ecosystem. It helps maintain a certain moisture level in an environment, depending on the number and types of plants in an environment. This inadvertently allows some organisms to survive better than others depending on the moisture levels that they need to thrive.
What is the difference between lenticular, stomatal and cuticular transpiration?
Difference Between Lenticular, Stomatal And Cuticular Transpiration In Tabular Form. It is the loss of water in form of vapor through the lenticels. It is the loss of water in the form of vapor through the stomata. It is the loss of water in form of water vapor through the cuticle.
What is transpiration in plants?
Transpiration is the process in which plants lose water in the form of moisture or water vapor. Parts of plant like stem, small pores on leaves and flowers evaporate the water to the atmosphere. 90% of the transpiration occurs through foliar surface or surface of leaves. Types of transpiration include: stomatal, ...
What is the loss of water in the form of vapor through the stomata?
It is the loss of water in form of water vapor through the cuticle. It occurs throughout the day and night. It occurs only during day time. Cuticular transpiration continues throughout day and night.
What is the process of vaporization in plants?
Cuticular Transpiration. Cuticular transpiration is the loss of water in form of vapor in plants through the cuticle. Water vapor directly diffuses through the cuticle on leaves and escape to the atmosphere. The cuticle is an impermeable, waxy or resinous layer of cutin, a fatty substance, covering the outside ...
What is the process of vapor getting out of a stem called?
These pores are referred to as Lenticels and therefore when vapor get out through these minute pores, the process is then referred to as Lenticular Transpiration or Lenticellate .
Why is cuticular transpiration higher than stomatal transpiration?
Cuticular transpiration rate can be higher than stomatal transpiration during extreme dry conditions due to stomatal closure. On the contrary, in plants having leaves with thin cutin cover, loss of water can be significantly higher under conditions that favor high rate of transpiration.
What are the different types of transpiration?
Types of transpiration include: stomatal, lenticular and cuticular transpiration. Below are is a detailed explanation of how they differ from one another.
