      \n(iii) under the fan
      \n(iv) covered with a polythene bag
      \nAnswer:
      \n(iii) under the fan<\/p>\n

      Question 4.
      \nWhy is the transport of materials necessary in a plant or in an animal? Explain.
      \nAnswer:
      \nThe cells of different organs of plants and animals need various necessary substances to carry out many metabolic activities and different types of waste products are created during these metabolic activities. So, the transport of materials is necessary to supply the required substances and to remove the waste products.<\/p>\n

      Question 5.
      \nWhat will happen if there are no platelets in the blood?
      \nAnswer:
      \nIf there are no platelets in the blood, then the blood would not be able to clot. A clot is formed because of platelets. They release blood-clotting chemicals at the site of injury. These chemicals form a clot and prevent further bleeding.<\/p>\n

      Question 6.
      \nWhat are stomata? Give two functions of stomata.
      \nAnswer:
      \nThe numerous pores under the surface of leaf are called stomata.
      \nFunctions of stomata :
      \na. Stomata help in the exchange of gases.
      \nb. Evaporation of water from the leaf surface occurs through stomata.<\/p>\n

      Question 7.
      \nDoes transpiration serve any useful function in the plants? Explain.
      \nAnswer:
      \nTranspiration is the evaporation of water from the plants. The water evaporates through the stomata present on the surface of the leaves. It is called a necessary evil because.<\/p>\n

        \n
      • It helps in lowering the temperature of the plant thus prevents heat injury to the plant.<\/li>\n
      • Due to transpirational pull water rises in higher plants. ,<\/li>\n
      • It also causes loss of water absorbed by plants.<\/li>\n<\/ul>\n

        Question 8.
        \nWhat are the components of blood?
        \nAnswer:
        \nThe main components of blood are :
        \na) Red blood cells (RBCs)Red blood cells are the most abundant cells in the blood these cells contain a red pigment called hemoglobin. It is the hemoglobin which carries oxygen and transports it to all parts of the body.<\/p>\n

        b) White blood cells (WBCs): These cells can change their shape and help the body in fighting against diseases thus, they constitute the immune system of the body.<\/p>\n

        c) Platelets: they help in blood clot formation thus prevents excessive bleeding from wounds.<\/p>\n

        d) Plasma: All the blood cells are present in plasma. It also contains dissolved nutrients.<\/p>\n

        Question 9.
        \nWhy is blood needed by all the parts of a body?
        \nAnswer:
        \nBlood is needed by all parts of the body as it is an important part of the transport system of our body. It performs the following important functions :<\/p>\n

          \n
        • It transports O2<\/sub> from the lungs to all the body cells.<\/li>\n
        • It carries CO2<\/sub>, a waste product back to the lungs, so that it can be exhaled easily.<\/li>\n
        • It transmits heat, thus regulating the body temperature.<\/li>\n
        • It also fights off diseases and infections.<\/li>\n<\/ul>\n

          Question 10.
          \nWhat makes the blood look red?
          \nAnswer:
          \nThe presence of hemoglobin, a red pigment in the red blood cells (RBC\u2019s) makes blood appear red in colour. The hemoglobin carries oxygen and transports it to all the parts of the body.<\/p>\n

          Question 11.
          \nDescribe the function of the heart.
          \nAnswer:
          \nThe human heart is divided into four chambers. The upper two chambers are called the right and left atrium and the. lower two chamber are called the right and left ventricles, right atrium receives carbon dioxide-rich blood from the body. Blood from right atrium enters the right ventricle, which contracts and pumps the blood to the lungs.
          \nOn the other hand, oxygen rich blood from the
          \n\"KSEEB
          \nlungs returns to the left atrium, from the left atrium, blood enters left ventricle. Left ventricle contracts and pumps the blood to all parts of the body. Hence, the rhythmic contraction and expansion of various chambers of the heart maintains the transport of oxygen to all parts of the body.<\/p>\n

          Question 12.
          \nWhy is it necessary to excrete waste products?
          \nAnswer:
          \nAll cells of our body produce waste products. These waste products are toxic to the body and therefore need to be executed out. This process of removing waste products produced in the cells of living organisms is called excretion.<\/p>\n

          Question 13.
          \nDraw a diagram of the human excretory system and label the various parts.

            \n
          1. It transports substances like digested food from the small intestine to other parts of the body.<\/li>\n
          2. It carries oxygen from the lungs to the cells of the body.<\/li>\n
          3. It transports waste for removal from the body.<\/li>\n<\/ol>\n

            Question 2.
            \nDefine Circulatory’ System.

            \nWhat are the Components of blood, state its function.
            \nAnswer:
            \nBlood Consists of Plasma (fluid) RBC, WBC and Platelets. Plasma is a liquid mainly contains Water. RBC means red blood cells which contains Haemoglobin a red pigment which gives red colour to blood and binds with oxygen and transports it to all parts of the body cells. WBC means white blood cells which fight against germs that may enter our body
            \nPlatelets are the types of cells present in the blood which help in clotting of blood.<\/p>\n
