Question

what is the role of transpiration in transporting water and minerals in plants?

Answer 1

The transpiration of water and dissolved mineral salts, from the root to the stem, leaves, flowers and other parts of the plants takes place through the xylem. ... The food prepared by the leaves is transported to all parts of theplant in the form of a solution through a process known as translocation.

Role of transpiration in plants

Explanation:

• Transpiration plays a vital role in the body of the plants, some of them are :
• It helps it to transport water and minerals towards the leaves from the roots in the upward direction against the gravitational pull  
• It cools down the plant during summers  
• It removes excess water
• Also when water is eliminated from the plant it urges the roots to pull more water and along with them minerals are also absorbed with is beneficial for the plant.
• The factors affecting water absorption are of three types:
• Physical factors: This includes the factors like soil water content, soil temperature, soil aeration and flooding.  
• Atmospheric factors: This includes factors like wind velocity, humidity, sunlight etc.
• Biological factors: This includes the factors like type of root system, morphology of leaves, growth stage ​of plant, stomatal mechanism and number etc.
• Tanspiration pull  :- When water gets evaporated from the surface of the leaves, in order to meet the requirements of the plant, the water is sucked up from the soil by the roots of the plant and is transported throughout the plant body i.e. from the roots of the plant till the leaves.
• Continuous evaporation from stomata of leaves creates suction which pulls up water through xylem vessels .This process of sucking of water from the soil, by the roots of the plant may be termed as transpiration pull.
• It is a basic process needed for the maintenance and the growth of the plant. This transports the water and all the essential nutrients from the soil to the various parts of the plant which are needed from its growth and maintenance.
