Question 3: Given below are the diagrams of a certain structure in plants in two conditions. After a few minutes the cohalt chloride paper shows change in colour from blue to pink. In the absence of transpiration, excess water will get accumulated in the plant cells, and the cells will eventually burst. (ii) They lose water vapour and process is termed stomatal transpiration. 3. This water deficiency in cells cause them to loose turgidity and the plants wilt. It causes around 20% of transpiration in plants. In this process, loss of water in the form of vapours through leaves are observed. The leaves of the Xerophytic plants have cuticular wax. Next lesson. Cobalt chloride paper 7. We provide step by step Solutions for ICSE Biology Class 10 Solutions Pdf. (iii) Transpiration is the loss of water in the form of water vapor through the aerial parts of the plant. After a few hours, CaCl2 vials were taken out and weighed again. Takes place through the stomata. It is instead lost through transpiration, the evaporation of water through the leaf surface and stomata, and through guttation, which is the loss of water from the vascular tissues in the margins of leaves. Transpiration 2. Question 4: Plants absorb more water than their requirement. Transpiration is the process of water loss from leaves of plants through stomata. Answer: Wind causes faster movement of air and remove the moist air and faster evaporation of water and therefore higher rate of transpiration. It has reticulate venation. Therefore, to prevent wilting they require excess of water. Occurs during the day when it is hot. Mainly it occurs at the leaves while their stomata are open for the passage of CO 2 and O 2 during the process of photosynthesis. The stomatal transpiration continues till the stomata are kept open. Eg. Weight of test tube B will remain same after the experiment because water will not be lost by transpiration as there is no plant in and nor by evaporation as oil is spread over it, which will not allow evaporation. During the day guard cells begin photosynthesis and the sugar produced during the process increases the osmotic pressure which draws in water from the adjoining cells. Sweat containing urea, uric add and salts are removed with water. More transpiration occurs from the upper surface of a leaf. 5. Loss of water from the surface of the water bodies in the form of vapour. Circulatory System and its Components. (iii) Water escapes through stomata and lenticels. It takes place through the sweat pores of the sweat glands. (v) 1. If the roots of land plants remain waterlogged, then lenticels will not be able to do gaseous exchange and as a result of this plants will die. They lose water vapour and process is called lenticular transpiration. To score more marks in your ICSE Class 10 Biology exam, you will have to write and practise the chapter questions and answers.
