Explanation:

Transportation in plants is an interesting process. It includes the transport of all the nutrients and water to all parts of the plant for its survival. In case of plants, the biggest concern is the transport of water and it terminates at the limiting factor depending on its growth. To overcome this problem, a tree uses several processes like Translocation, Storing, Absorption and Utilization of water

Definition of Transportation in Plants

Transportation is the process of transporting water, minerals and food to all parts of the plant body.

Transport in plants occurs at three levels:

The uptake and release of water and solute by individual cells.

Short distance transport of substances from one cell to another.

Long distance transport of sap within xylem and phloem.

Definition of Translocation

Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but non-photosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.

In other words, translocation is the movement of water and other nutrients from soil to all parts of the plant.

Direction of Transport

Direction of transport is an important aspect in plants. In case of rooted plants, transport in xylem of both minerals and water is unidirectional from roots to stems. In this, mineral and organic nutrients undergo multidirectional transport. It includes the organic compounds that are formed during photosynthesis are exported to all parts of the plants along with storage organs. Plant growth regulators, hormones and chemical stimuli are also transported in unidirectional or polarized manner, in very small amounts, from where they are formed to other parts.

Means of Transport

There are three means of transport as follows:

Diffusion

Facilitated diffusion

Active Transport

Question :

What is transpiration? How it is useful for plants?

Answer :

~The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface.

~This is transpiration.

It has two main functions:

1. Cooling the plant and
2. Pumping water and
3. Minerals to the leaves for photosynthesis.
