Q: 4. What is the significance of transpiration?

The significance of transpiration is as follows:A cooling effect is achieved by taking up the plant's heat and converting it to water vapour that is then expelled during transpiration.In order to maintain healthy and normal growth, optimal Turgor pressure needs to be maintained as the plant absorbs excess quantities of water which are released during termination.By creating a transpiration pull, it aids in the transportation of minerals absorbed from the soil by the roots, resulting in a more balanced distribution of minerals.A transpiration pull results in a continuous supply of water to the top by creating a transpiration pull.

Transpiration

Transpiration is the process by which leaves and stems lose water in evaporation. A plant releases moisture through transpiration, which is the process of carrying moisture from its roots to small pores on the underside of its leaves, where it changes into vapour.

Types of Transpiration:

1. Stomatal Transpiration

Plants lose most of their water through transpiration, which is the most dominant form of transpiration. Leaf transpiration accounts for 90-95% of all water loss from plants. It is a process in which microscopic pores in the epidermis of the leaves, known as stomates, participate.

2. Cuticular Transpiration

In plants, this kind of transpiration causes the loss of water through the cuticle. On leaves and herbaceous stems, water vapour diffuses directly through the cuticle and escapes into the atmosphere. Leaf cuticles are waxy or resinous layers of fatty material that cover the outside (epidermis) of plant leaves.

3. Lenticular Transpiration

Plants lose water through transpiration when there is a vapour exchange between their lenticels. Plants have lenticels in woody stems, twigs, and other organs where tiny openings protrude from the bark. Similar to cuticular transpiration, lenticels are not able to expel enough water vapour when compared to stomata.

Thus, Vedantu Transpiration Solutions for ICSE Board help students prepare well for the exam in the best possible way.

2. How does the opening and closing of stomata regulate the transpiration process?

There is an abundance of pores on the lower epidermis of the leaf called stomata. Stems are also covered with them. By means of the stomata, gaseous exchanges and transpiration are affected. Two guard cells surround the stomata and control their opening and closing. To exchange gases and release water vapour through transpiration, stomata open during the day. In the guard cell, a change in turgor pressure causes the stomata to open and close. As a result of greater transpiration pull, roots absorb water during the day and it is transported through the xylem to different parts of the plant. When this water is received by the guard cell, it swells and becomes turgid. Due to which the stomatal pores are open.

3. What are the drawbacks of transpiration?

Although transpiration has various advantages, there are disadvantages as well.

a. Wilting: During noon, a plant often wilts or loses its turgidity because transpiration is much higher than water absorption. During wilting, the rate of photosynthesis and other metabolic activities decreases.

b. Reduced Growth: The loss of water through transpiration reduces the amount of water available to the plant. Lack of water leads to stunted growth, which makes the plant look unhealthy.

c. Abscisic Acid: Abscisic acid is formed when there is a water shortage. Abscisic acid inhibits several plant processes, including leaf, flower, and fruit abscission.

4. What is the significance of transpiration?

The significance of transpiration is as follows:

A cooling effect is achieved by taking up the plant's heat and converting it to water vapour that is then expelled during transpiration.
In order to maintain healthy and normal growth, optimal Turgor pressure needs to be maintained as the plant absorbs excess quantities of water which are released during termination.
By creating a transpiration pull, it aids in the transportation of minerals absorbed from the soil by the roots, resulting in a more balanced distribution of minerals.
A transpiration pull results in a continuous supply of water to the top by creating a transpiration pull.
