Expert Answer:

Plants and animals require special transportation tissues and organs so as to ensure that the nutrients and other essential substances reach all of their cells as and when needed. Also the wastes produced have to be removed from the cells in less time. All of these processes should be carried out quickly to help in the survival of animals and plants.
