FAQs on Transpiration Solutions for ICSE Board Class 10 Science
1. Do I need to practice all the questions for Transpiration given in the Concise - Selina?
You will become more familiar with transpiration concepts as you practice more. As a result of the Concise wide collection of questions, you will not only be inspired to think creatively, but also able to demonstrate your mastery of concepts. By on-the-spot learning, you will be able to apply every concept in the correct situation. Taking into consideration all the questions given in the chapter is important. Therefore, it is always advisable not to leave any questions or topics from the textbook. Furthermore, you will be able to analyse your preparation for the exam by practising worksheets, sample papers, and mock tests. 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.
