Which part of the plant absorbs nutrients?

1. Stem

2. Flowers

3. Leaves

4. Roots

The correct answer is: Roots

The roots are known as the "lifeline" of the plant, as they are responsible for absorbing water and nutrients from the soil. The stem and flowers are mainly responsible for transporting water and nutrients throughout the plant, while the leaves are primarily responsible for photosynthesis. However, the main function of the roots is to anchor the plant and absorb vital nutrients from the surrounding soil. Without the roots, the plant would not be able to grow and thrive. This makes the roots the most important part of the plant for absorbing nutrients.
