Question: 1 / 400

What is the primary function of roots in a plant?

To produce food through photosynthesis

To anchor the plant and absorb water and nutrients

The primary function of roots in a plant is to anchor the plant and absorb water and nutrients. Roots provide stability, helping to secure the plant in the ground, which is essential for supporting the plant, especially as it grows tall or wide. Additionally, roots are responsible for drawing in water from the soil and nutrients essential for the plant's growth and development.

While other plant parts have specific roles, like leaves producing food through photosynthesis or stems transporting nutrients and water, roots primarily focus on anchoring the plant and enabling it to take up the necessary resources from the soil. This makes them crucial for a plant's survival, as adequate water and nutrients are vital for growth and overall health.
