Question

Raj has a small garden. He was watering the plants and he over flooded a pot. He was wondering what happens to the root pressure in that plant. Choose the option that describes what would have likely happened.

• A. The root pressure remains unchanged.
• B. The root pressure increases.
• C. The root pressure decreases.
• D. The root pressure decreases and then increases.

Answer 1

The correct option is B The root pressure increases.

Water enters the root through the process of osmosis. The water on entering the cells makes it turgid. These cells exert pressure on the neighbouring cells. This is called root pressure. Root pressure helps in pushing water to small heights.
When the pot is flooded, more water surrounds the roots making more water to enter it. As more and more water enters the root, the root pressure increases.
