Question

In a tall tree, which force is responsible for pulling water and minerals from the soil?

• A. Gravitational force
• B. Transportation force
• C. Suction force
• D. Conduction force

Answer 1

The correct option is C

Suction force

The correct option is C.

Explanation of the correct option:

Option C:

1. The transpiration pull is the force responsible for pulling water from the roots to the stem.
2. Transpiration pull is created by the process of evaporation.
3. It creates a suction, which pulls minerals and water from the soil.
4. Hence, this draws water into the leaves via the capillary action.
5. The water is used to perform the process of photosynthesis and the rest is lost as water vapors through the stomate.

Explanation of the incorrect options:

Option A:

1. Gravitation force is responsible for keeping all mass to interact with each other and attract one another.
2. It is a universal force.
3. It is a huge force that acts over long distances.
4. 9.8 ms^-2 is the value of at earth's surface due to gravitational force.
5. This is an incorrect option as gravitation pull does not assist in pulling water and minerals.

Option B:

1. The transportation force is used when the movement of goods or objects occurs from one place to another.
2. Hence, this is an incorrect option, as the transportation force is not responsible for pulling water and minerals.

Option D:

1. The force of conduction is applied when there is a transfer of heat energy or electricity directly via contact.
2. The force of conduction does not help to pull water and minerals in plants.
3. It is an incorrect option.

Final answer: In a tall tree, the force responsible for pulling water and minerals from the soil is suction force.
