Transpiration is the loss of water from the living tissues of the aerial parts of the plant in the form of water vapours. Transpiration is a very important process not only for the plant but also for the environment. Role of transpiration in material transport:  The blood maintains water balance to constant level by distributing it uniformly in the body. Frank ICSE Class 10 Biology Solutions – Transpiration PAGE NO:60 Solution 1: Transpiration: It is the loss of water in the form of water vapour from aerial parts of the plant. During transpiration, water comes out in the form of water vapour. 4. What do you mean by cuticular transpiration? Two percent of total water absorbed is used up in various metabolic activities in the plant body. if the amount of hemoglobin in blood is less, the person suffers from anemia The hemoglobin carries oxygen to the different cells of the body and brings carbon dioxide from the cells. (C) It regulates the temperature of the plant. Primary reason: it brings water to the leaves for photosynthesis. ICSE Solutions for Class 10 Biology – Transpiration. 5.1 (b) Detection of Normalcy of Heart Beat : The muscle fibres of heart are specialized at certain parts generate tiny electrical currents which cause the normal heart heats. Answer : Odd term : Phagocytosis. They exchange gases from the external environment directly by diffusion due to the difference in the concentration in and outside their body. Heart is a hollow muscular organ that lies obliquely in the thoracic region in a cavity between the two lungs that is pericardial cavity. 1. The transpiration plays a significant role in expanding the root base. Important Question for Class 10 Science Life Processes PDF will help you in scoring more marks.. Our Biology experts have provided answers for ‘True or False’ questions from your textbook with supporting reasons for each answer. 1 Mark Questions Answer : Lenticels help in facilitating the process of transpiration in woody plants. It creates a negative pressure gradient that helps draw water and minerals up through the plant from its roots. (ii)   It carries mineral salts, water and               (ii)           An organic solution of sugars and amino acids is. Lack of growth: The growth of a plant is significantly affected by the water availability for that plant. Transpiration also includes a process called guttation, which is the loss of water dripping off uninjured leaf margins of the plant but plays a minor role in transpiration. Answer : Balsam is a herbaceous plant that loses too much of water by excessive transpiration, i.e., the rate of transpiration is more than the rate of absorption. Unicellular organisms e.g. Our counselor will call to confirm your booking. This is called “systolic pressure”. In granulocytes the cytoplasm contains granules and the nucleus is multliobed. (iii) It supplies digested food and oxygen to various parts of the body. (i)    Functional xylem ells are dead. The digested and absorbed nutrients like glucose, amino acids, fatty acids are first transported to the liver and then to all the tissues for their storage, oxidation and synthesis of new substance. The whole process  can be compared with a person (transpiration pull) pulling a bucket full of water (forces on water column) from a well with a rope (column of water due to cohesion). Neighbouring body muscles help in the flow of lymph. We understand the need and importance of revision notes for students. Tricks for Proper Utilization of Add-On 15 Minutes introduced in CBSE Board Exams ; The transpirational pull: when the plant loses water through transpiration from the leaves, water and mineral salts from the stem and roots moves, or is `pulled', upwards into the leaves. Transpiration is the loss of water in the form of water vapours from the aerial parts of the plant.. The disadvantages of transpiration are:-a)Excess of transpiration retards the growth and development of plants The lymph is the tissue fluid present in the intercellular spaces in the tissues. Transpiration: Water loss from the aerial parts of the plant is called transpiration. Lymphatic system runs parallel to the veins.

Rather the blood of donor is always cross matched before transfusion to exclude any change of incompatibility. White blood corpuscles are of two types : (C) Blood platelets : These are small and without nuclei. (D) Mostly water absorbed by roots is lost by transpiration without serving any purpose. Wilting: Wilting caused by lack of water availability or increased transpiration can dry up the plant and finally kills the plant. The erythrocytes contain hemoglobin. Good quality fruits and Increasing concentration of mineral salt:With transpiration, the sap solution inside the plant becomes concentrated. Ascent of sap and removal of excess water: Transpiration helps to maintain a proper balance of water in plants since plants have a tendency to absorb more water than needed. Revise the purpose of a potometer with an appropriate diagram. The number of leucocytes increases in infections like. Role of transpiration in photosynthesis: Transpiration-pull caused by transpiration provides the water needed for photosynthesis and other metabolisms such as respiration. Abscisic acid: Water stress produces abscisic acid which promotes abscission of leaves and fruits. one ml of blood contains 5000 - 10000 leucocytes in humans. This lactic acid is carried to the liver for further oxidation. Role of transpiration in maintaining temperature: Fats and anxiety increase the blood pressure, the maximum normal blood pressure should into exceed 150 in males and 140 in females. Root hair are the extensions of the epidermal cells. For each antigen there is a corresponding antibody. For this all major hospitals have blood banks where blood is collected from voluntary and professional donors. The total number of WBCs is about 75 millions. traces of organic molecules                                          translocated. These are in direct contact with their surroundings from where they obtain these nutrients. These hormones have target organs (p lace to act). Transpiration is very important for maintaining moisture conditions in the environment. Larger lymphatic vessels unite to form large ducts i.e. Write a short note on advantages and disadvantages of transpiration. The lymph is the tissue fluid present in the intercellular spaces in the tissues. (A) It controls the rate of absorption of water from the soil. First of all, transpiration drives the "circulatory" system of the plant. It is done through circulatory system. Though theoretically a patient may be able to receive blood of two or more types, it is always advisable to have the donor blood of the same group as that of the recipient. Transpiration—the loss of water vapor to the atmosphere through stomata—is a passive process, meaning that metabolic energy in the form of ATP is not required for water movement.The energy driving transpiration is the difference in energy between the water in the soil and the water in the atmosphere. (i) Blood : The blood is a specialized kind of living connective tissue which is made to circulate, by the muscular pumping organ called as the heart. The blood pressure varies according to the contraction and relaxation of the heart. In the plasma RBCs, WBCs and blood platelets float.

Chapter 6 Life Processes Class 10 Science Important Questions and Answers PDF will help you in scoring more marks. In the mechanism of opening and closing of stomata, the important factor is : (a) The presence of chloroplast in the guard cells (b) The turgid and flaccid state of the guard cells The transpiration process helps in reducing this temperature hike and provide a cooling effect for the plant. Transpiration is the evaporation of water from plants. There are four types of blood groups depending on the presence or absence of these antigens. Transpiration takes place in leaves through stomata. It can be corrected by the surgical grafting of an artificial pacemaker instrument in the chest of the patient. These are large in size and contain nucleus. The transportation of material is carried out by means of vascular tissues of the 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. Water evaporates from the surface of the cells into the air spaces of the spongy tissues and then passes into the outer atmosphere through the pores or stomata. The cohesion-tension model works like this: Transpiration (evaporation) occurs because stomata are open to allow gas exchange for photosynthesis. Fibrin forms a network which entangles RBCs and blood platelets to form plug or clot over the inured area. Four pulmonary veins enter into left auricle, two from each lung bring oxygenated blood. Due to these adhesive and cohesive forces, water column does not break but pulled upward by the force called as, The blood is a specialized kind of living connective tissue which is made to circulate, by the muscular pumping organ called as, The plasma consist of water (90% & above) inorganic substances.
