Question

Water enters into root hairs due to

• A. Turgor pressure
• B. Osmotic pressure
• C. Elastic pressure
• D. Atmospheric pressure

Answer 1

The correct option is B

Osmotic pressure

1. Osmosis is the process of movement of water from a higher water concentration region to a lower water concentration region.
2. The absorption of water and minerals is the function of the root hairs that are present in millions at the tips of the roots.
3. Due to the osmotic pressure, water enters inside the roots and is transported to all parts of the plant.
4. Hence, the correct answer is osmotic pressure.
