There are four types of blood groups depending on the presence or absence of these antigens. Nutrition,respiration, etc. All living bodies need nutrients and oxygen in every cell of its various tissues to sustain life. Hence, lesser yield. It is done through circulatory system. Question 6 What is translocation? (i)    Functional xylem ells are dead. It helps in maintaining the level of CO2 and O2. The significance of transpiration is explained below: Transpiration helps in the conduction of water and minerals to different parts of the plants. The respiratory gases (oxygen, carbon-dioxide) are transported by the blood. 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. Since approximately 90 percent of absorbed water is lost through transpiration, the energy used in absorption and conduction of water goes waste. It creates a negative pressure gradient that helps draw water and minerals up through the plant from its roots. These are filled with a fluid called “pericardial fluid”. Fibrin forms a network which entangles RBCs and blood platelets to form plug or clot over the inured area. 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. The transpiration provides the mechanical strength which provides rigidity for the plant. Transpiration is the evaporation of water from plants. During transpiration, water comes out in the form of water vapour. The energy spent by the plants in transpiration is wasted. As a result water is sucked from adjoining mesophyll cells and ultimately from vascular tissues. These help in blood clotting at the site of injury by liberating Thromboplastin. (B) White Blood Corpuscles (WBCs) or Leucocytes: The number of leucocytes is comparatively fever i.e. Neighbouring body muscles help in the flow of lymph. Circulatory system consists of blood vascular system (blood as carrier) and lymphatic system (lymph as carrier). All the other three terms are concerned with processes in plants. Primary reason: it brings water to the leaves for photosynthesis. The blood acts as the circulatory fluid. The ends of lymphatic capillaries are blind. The WBCs (eosinophils, neutrophils, monocyts) engulf the bacteria and other disease causing organisms by phagocytosis. Watch concept videos to understand the significance of stomatal transpiration.

These substances are distributed in the cytoplasm due to the streaming movements of cytoplasm called as cyclosis. The blood pressure is measured by “sphygmomanometer”. Heart is a hollow muscular organ that lies obliquely in the thoracic region in a cavity between the two lungs that is pericardial cavity. (v)  It returns proteins and excess tissue fluid to the blood from the tissue spaces. The lymph resembles the blood except that the lymph is devoid of R.B.Cs, blood platelets and some plasma proteins. As a considerable amount of water is lost in transpiration, the plant might shunt its growth. Excessive rate of transpiration leads to stunted growth of plants. However, transpiration is tightly controlled. Their number various from 0.15 to 0.45 million in 1ml of blood. It is often needed during accident and operation. Each RBC is a biconcave disc-like structure devoid of nucleus. Their normal life span is one week. Both people lead normal life. Role of transpiration in the absorption of water and minerals: Stomata consist of guard cells, epidermal […] Transportation of metabolic intermediates : The blood carries metabolic intermediates from one tissue to another for further metabolism. Sunlight falling on the leaves increases the temperature on it, which can be harmful to the plant. Bosophils, Eosinophils and Neutrophils are three different types of granulocytes. Role of transpiration in maintaining temperature: Lymphocytes and other plasma cells are present in the lymph nodes. The lymphocytes produce antibodies to neutralize the action of toxins produced by pathogens. The water absorbed by the soil will have less concentration of salts which is not ideal for the plant growth. Right ventricle has pulmonary valve having 3 semilunar cusps for pulmonary artery carrying deoxygenated blood to lungs. The total number of WBCs is about 75 millions.
