Match the two columns: Column A Column B 1. Carrier of oxygen A. White blood cells 2. Liquid part of blood B. Heart 3. Blood cells which fight against infection C. Haemoglobin 4. Pumping organ D. Plasma 5. Toxic to organisms E. Waste products 6. Transpiration F. Stomata

1 - C Haemoglobin is the iron-containing protein present in the red blood cells. It carries oxygen to all the parts of the body. 2 - D Plasma is the clear, straw-coloured liquid portion of blood. It contains proteins, nutrients, electrolytes and water as a major component. 3 - A WBCs, also called leukocytes, are an important part of the immune system. These cells help fight infections by attacking bacteria, viruses, and germs that invade the body. 4 - B The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. 5 - E Waste products are toxic to human beings as they can harm the normal functioning of the body. These products are excreted by the help of the excretory organs such as kidneys, lungs and skin. 6 - F Transpiration is the process of water loss in the form of water vapour through pore like structures called stomata. Thus, the final answer is : Column A Column B 1. Carrier of oxygen C. Haemoglobin 2. Liquid part of blood D. Plasma 3. Blood cells which fight against infection A. White blood cells 4. Pumping organ B. Heart 5. Toxic to organisms E. Waste products 6. Transpiration F. Stomata
