Plants generally are known to possess supporting tissues which give them definite shape, strength, rigidity and resistance against external forces such as wind and water to which they are continuously subjected.
As I discussed in an earlier post about means of transport system, the medium or means of transport in plant is latex or cell sap and the materials transported are water, carbon dioxide, oxygen, amino acids, e.t.c. Plants require sufficient quantities of several minerals and other substances which are transported in them.

The movement of blood in the body is made possible with the aid of the heart and blood vessels. The heart is responsible for the pumping of blood around the body and the blood circulates through the blood vessels.

Materials are efficiently distributed in mammals, especially man is provided by the transport system. The blood and lymph are the means of transport in man.

Transport systems refer to the systems of organs and tissues involved in the movement of materials, from where they are produced to where they are needed within various parts of an organism. This transport occurs in plants and animals.
