Brief introduction of Chapter 11 Transport in Plants

Julius Sachs is known as the father of plant physiology. Plants are variable in height ranging from a few centimetre centimetres to 130 meters. Now there is a question How does such long-distance transportation of water, mineral, and food take place in plants? Also, we know that plants do not have any circulatory system like animals.

In the chapter anatomy of flowering plants, we have gone through two important complex permanent tissues that are xylem and the phloem.

Short-distance movement in plants like the movement of molecules within a cell or between adjacent cells can take place by diffusion. In plants, diffusion is only the means of transportation of gases.

Xylem in plants is responsible for the unidirectional conduction of water and minerals. Water and minerals are absorbed by roots from the soil. In roots, apoplast and symplast are responsible for the movement of substances.

The exchange of gases between the plant body and the atmosphere takes place largely with the help of stomata present in the leaf epidermis. 

A concentration gradient is maintained for the movement of substance between two points.

Water potential is the free energy of water that is the tendency of the flow of water.

In this chapter, we will also get insight into how various force like transpiration pull, root pressure, and adhesion – cohesion is responsible for the ascent of sap.

Transport of photosynthates from source to sink to sink is bidirectional and takes place in masses or bulk by phloem.
