What is the Root System?

The root system is the part of a plant that grows underground. Roots help plants stay in the ground, find water, and take in nutrients from the soil. They are very important for the plant's health and growth.

Example: A carrot has a root system that helps it grow strong in the soil and store energy.

Fun Fact: Some plants have very deep roots that can reach water far below the ground, helping them survive in dry areas!

Why is the Root System Important?

Roots are important because they help plants stay steady, gather food, and drink water. Without roots, plants cannot live because they would fall over and would not get what they need to grow.

Example: A tree needs strong roots to stand tall and not fall during a storm.

Fun Fact: Some roots can even help clean the soil by taking up bad stuff that can harm plants and animals!
