The roots of a plant are primarily responsible for taking up water from the soil. They are specialized structures that extend into the ground, where they can access moisture and minerals that are essential for the plant’s growth and survival. Roots have tiny hair-like structures that increase their surface area and enhance their ability to absorb water and nutrients from the surrounding soil.

In addition to their role in water uptake, roots also anchor the plant securely in the ground, preventing it from being easily uprooted by wind or erosion. The absorbed water is then transported through the stem to the leaves, where it is utilized in processes like photosynthesis.
