• A. Push, air
• B. suction, water
• C. Push, water
• D. suction, air

Answer 1

The correct option is B suction, water

• The suction force is a type of force by which water is sucked upwards.
• In plants, due to transpiration – a suction force is created when water is sucked from the xylem in the roots to the stem and the leaves.
• The suction force will be greater wherever the diameter of the xylem cells is narrower and vice -versa.
• It is a form of loss of excess water by plants-meaning that anything in excess of what is needed by the plant for nutrition and metabolism will be released as transpiration.
• As a result, the plants do not get overheated and remain in stable conditions.
