Q12.72P - Chemistry: Molecular Nature Of Matter And Change

Question

A drooping plant can be made upright by watering the ground around it. Explain.

Step-by-Step Solution

Answer

Watering the area around a sagging plant will help it stand up. This is because of the capillary action of the water which provides the water to the plant phloem, thus making it upright.

Capillary action

Capillary action is the action where the movement of liquid takes place against gravity due to the cohesive forces in between the liquid molecules and the capillary wall.

Upright movement

When watering the ground around the drooping plant, the water actually reaches the root of the plant. Now, because of the capillary action, the water rises through the stem of the plant and passes water to the xylem, phloem, etc. this makes sin upright standing of the plant.
