The plants were wilting in a garden and the gardener watered the plants.
The plants became fresh again. Which
part of the plant is responsible for
conducting water in it and how does the process of conduction of water
take place in plants ?
Answers
Answer:
Answer is as follow:
- (i) Wilting is loss of rigidity from non woody parts of plant. This happens when the cells of plant tissue especially leaf have very less amount of water or no water.
- (ii) Conduction of water is carried out by a vasular tissue called xylem. Whereas, roots intake water in plant body trough hairs present at the tips.
- (iii) This process is carried out by a transpirational pull. This process is unidirectional and dies not require any energy .

Answer:
Xylem is responsible for conducting water in plants.
Explanation:
Wilting is the name of the event when non-woody parts of plants lose their rigidity. It occurs when the rate of loss of water from plants is greater than the absorption of water inside the plant which causes drying of the plant.
Since conduction of water is completely dependent on xylem so if xylem is removed or blocked then wilting will occur.
Process of conduction of water
Plant water relations include three interrelated processes which are as follows:
- Water absorption
- Ascent of sap
- Water loss by transpiration
Another physiologically important area of plant water relations is the plant water balance, which is controlled by the relative rates of water absorption and water loss.
The absorption of water is dealt with under three major headings which are as follows:
- The absorbing system
- The mechanisms involved in absorption
- Factors affecting absorption
The absorption of water is affected by a variety of plant and environmental factors. Transpiration from plants can be considered primarily as a physical evaporation process in which the rate of water loss is conditioned to a degree by the anatomy and physiological behavior of the plant. The transformation of liquid water to the vapour phase occurs at the moist surface of the mesophyll cells, with consequent diffusion of the water vapour into intercellular leaf spaces and diffusion through the stomata into the atmosphere.
