During the gaseous exchange or from barks, stems, or other parts through pores, the excess water absorbed by roots and which remain unused is lost to the atmosphere in the form of water vapors. The amount of water lost by plants over a period of time refers to the rate of transpiration. Transpiration rate is affected by a series of environmental and other morphological factors. The 10% of the atmospheric moisture is contributed by the transpiration whereas the rest of it is from the evaporation. ... Selina solutions for Concise Biology Class 10 Icse chapter 5 (Transpiration) include all questions with solution and detail explanation. Transpiration is of three types, based on the mode of water loss. During scarcity of water, roots absorb less water from the soil. Transpiration - "Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere ... Transpiration also includes a process called guttation, … Pro Lite, Vedantu Less than 3% of total water absorbed by plant is utilized by plants for the development and metabolic processes. VERY SHORT ANSWER TYPE ICSE Class 10 Transpiration. For good health and cellular growth, the water needs to be excreted out. Cuticular transpiration accounts for around 5%- 10% of the total water loss. 3. So, during day time photosynthesis and stomatal transpiration occurs simultaneously. Lenticular transpiration refers to water loss in the form of vapors through the lenticels of the plant. Too much of transpiration may lead to dehydration and damage to the plant. ; Plants prepare their food by photosynthesis. 1 Answer +1 vote . See more. Transpiration pull creates a pressure gradient that helps draw water and minerals up to the plant body from the roots. Transpiration pull is the biological process of force by which the plants draw water in the upward direction. Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Although transpiration is an unavoidable phenomenon that takes place during the gaseous exchange in plants, it’s necessary and has its own set of benefits for the plant. It promotes the proper growth of plants and cell division. 2. Adaptations in plants to reduce transpiration to be discussed. excretion is also an important life process. Answer: Each stomata is surrounded by guard cells. The pores in the tissue act as a pathway for gaseous exchange and transpiration. Define transpiration. To score more marks in your ICSE Class 10 Biology exam, you will have to write and practise the chapter questions and answers.

TRANSPIRATION The loss of water in the form of vapours from the living tissue of the aerial part of plants is called transpiration. ICSE Class 10 Biology Transpiration. Structured/Application/Skill type | Q 6.3 | Page 67. Roots absorb water from the soil in order to transport it to the plant parts for photosynthesis. Namely, stomatal transpiration- when it occurs through the stomata. It has various advantages for the plant body, which we will follow in detail. Depending upon the means by which transpiration is taking place it is divided into three types. High temperature decreases relative humidity, which forces the stomata to open even in the dark, thus increasing the rate of transpiration. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. The surface of mesophyll cells in leaves release a thin layer of water. Question 7 How does transpiration help in upward movement of water from roots to leaves? Hence, water in the form of vapor is lost through this layer. When transpiration takes place through leaves, it is foliar transpiration. Thus, transpiration can be defined as the process by which the plant body releases water in the form of vapors through its aerial parts. Pro Lite, Vedantu Transpiration is very important for maintaining moisture conditions in the environment. The remaining water is released by the plants into air as water vapour through the small pores in their leaves (called stomata). Absorption of water and transpiration is a cyclic process. This results in the closing of the stomata and even wilting. The process by which this water leaves the plant body is called transpiration. Short answer questions. 2. class-10; Share It On Facebook Twitter Email. 1. The remaining 97–99.5% is lost by transpiration and guttation. Question 6.

(10) Class VII Social Science (29) Class VII Hindi (6) Class VII Computer (6) Class VI Maths … Like all other life processes (eating, digestion, growth, etc.) This loss of water in the leaves exerts a pull on the water in the xylem ducts and draws more water into the leaf. Cuticular transpiration: Cuticle is an impermeable covering present on the leaves and stem. Rate of transpiration greatly depends on environmental factors such as: Stomata only open in the presence of light. ICSE Class 10 Biology Transpiration. Lenticels are a porous tissue found on the barks of woody stems and roots of dicots. What are the factors which affect Transpiration? Question 8 Explain the mechanism of transport of minerals in plants? Cuticles are waxy covering on the epidermis of the leaves. In Stomatal transpiration, water in the surface of the leaves is evaporated into the atmosphere when the stomatal opening opens. Plants leaves have microscopic openings on the epidermis which are meant for gaseous exchange and transpiration. Experiments on transpiration include demonstration of transpiration, determining site of greater transpiration, relation with absorption and suction due to transpiration. All Activity; Questions; Unanswered; Categories; Users; Ask a Question; Ask a Question. 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. (c) When the weight of the test tubes A and B is taken before and after the experiment, what change is observed? This water also evaporates and the water vapors diffuse into the sub stomal space, which finally diffuses out by stomata. Transpiration is important because a) It helps in absorption and upward movement of water and minerals from roots to leaves. TopperLearning’s chapter resources for ICSE Class 10 Biology – Transpiration will help you grasp the concept of how plants lose water vapour. The cuticle is a waxy covering on the surface of the leaves of the plants. Transpiration also refers to the evaporation of water from the plant part.

Stomatal transpiration accounts for 85%- 90% of the total water loss in plants. Hi sir can you tell any four advantages of transpiration???? The loss of water from plants as water vapour through the pores of their leaves is called transpiration. The stomatal opening opens when light falls on it. Stomatal transpiration is one form of foliar transpiration. In such atmospheric conditions, water vapors accumulate around the transpiring organs and reduce the rate of diffusion. - American Geological Institute, 1976. Give the technical terms for the following: Answer: (a) Growth dependent movement in plants. Trophic … Two types of forces, cohesive and adhesive force work together to bring about this upward pull. It is an important process in plants that facilitates other processes and keeps a balance of water and nutrients. Also, the cell sap of cells in leaves exert pressure on the outward of the cell wall. ; Stomata help in exchange of gases, which is intake of carbon dioxide and release of oxygen in the presence of water and sunlight by the process of photosynthesis. This thin water layer then evaporates. The Questions and Answers of what is translocation? The process of transpiration puts a large amount of water vapour into the air. State its two functions. Water is continually being lost from leaves by transpiration. Transpiration is the process by which excess water in plants is lost to the atmosphere in the form of water vapour through tiny pores present on the surface of the leaf called stomata.
