The transport system in plants is similar to the circulatory system in animals and human beings. However, it is different in several important ways. There is no pump like the heart, no circulating cells and liquids do not continuously move round and round.

Mineral salts from the soil and the products of photosynthesis are the substances which are transported. These substances are what gives the plant fuel.

When you look plant material in a microscope, you will see it as a mass of cells, rather than tubes like blood vessels.

Water and mineral salts enter a plant through special cells. The water is taken up by a kind of diffusion, but the mineral salts (ions) may also be taken up by active transport which uses some of the plant's energy to concentrate them.

Some of the main vessels take nutrients into the plant. They are called Xylem vessels and carry water and minerals. The water and minerals come from the roots that are in the soil.

Other vessels carry sugars and foods such as amino acids produced as a result of photosynthesis.

Plants have a transport system, in some ways similar to an animal's blood circulatory system. However, it is rather different in several important ways. For example, there is no pump like the heart, no circulating cells and liquids do not continuously move round and round.


The substances which are transported - mineral salts (ions) from the soil, and the products of photosynthesis from the leaves - are dissolved in water (as an "aqueous solution"). The transport system basically consists of 2 types of conducting tissue, each of which is made from cells which have been modified for their special purpose. Some cells die as a result of this modification, and they may also lose some of their internal components.


When you look at sections of plant material, you will see this tissue as a mass of cells, rather than easily defined tubes like blood vessels in animals!

Water and mineral salts enter a plant through special cells called root hair cells. The water is taken up by a special form of diffusion called osmosis , but the mineral salts (ions) may also be taken up by active transport which uses some of the plant's energy to concentrate them.


Xylem vessels carry water and minerals on into the plant, but only in an upward direction. These vessels form a continuous "pipe" from the root to the stem and leaves.

The movement of dissolved substances into and out of cells or tissues in plants is termed as transport. The entry of dissolved substance into the cell is called influx and its exit is called eflux.Various theories have been put forward from time to time to explain the mechanism of solute absorption. They are broadly categorise into two groups based on the involvement of metabolic energy in the process. Those which believe that metabolic energy is not involved in the solute absorption have been grouped under Passive transport and those which believe that metabolism and metabolic energy is involved in the process have been placed under Active transport. Passive transport occurs through the layer of protoplasm between the cell wall and the vacuole from its higher to lower chemical potential. Whereas the active transport of a substance occurs across a protoplasmic membrane from its lower to higher chemical potential, i.e., against a concentration gradient
