Answer.

Transport of materials is very important for the survival and development of living organisms. If transportation never existed, then no life on earth could be possible. The following is an outline of the importance of transport of materials in living things:

1. It facilitates the removal of waste materials from the organism’s body, the excess of which could harm an organism.

2. It ensures that essential materials like oxygen, nutrients, water, hormones and mineral salts are supplied to the cells and tissues as required.

3. It enables essential substances to move from one part of the body to another. For example,food manufactured by photosynthesis in plant leaves is transported from leaves to other organs of the plant for use or storage.
