The hormones are synthesised far from their site of action. Thus, blood is necessary for transporting the hormone..

Some of the carbon dioxide is transported in haemoglobin. However, most of the carbon dioxide is transported as bicarbonate ions. Carbon dioxide first combines with water to form carboxylic acid. This then splits into hydrogen ions and bicarbonate ions. The hydrogen ions a..

Food is manufactured in the form of carbohydrates (sucrose) in the leaves. Thus, food is transported as sucrose along phloem. From the leaves the prepared food has to be transported to the roots, the younger top regions of the plant, the flowers and fruits. Thus, the food ..

As mentioned earlier, the transport in higher plants is with the help of the vascular system. Thus, these plants are also called the vascular plants..

Introduction - In unicellular organisms a single cell carries out all the life processes as the cell itself is the organism. In advanced forms like the few-celled algae, protozoa, sponges, etc., the size of the organism ensures that all the cells are not very far from each other. The uptake of mate..

Materials to be transported include digested food, respiratory gases, hormones, excretory products, etc. The digested food includes sugars like glucose, amino acids, fatty acids and their derivatives. Blood which is the vascular tissue in man is over 90% water. Thus, only the water-solubl..

Circulatory System - The transport system in animals is called the circulatory system. The materials are transported from one part of the body to another by a mass flow system which is the circulatory system. The animals, particularly the more advanced forms, have a higher metab..
