What is one of the key functions of roots?

Roots play a vital role in plant development and survival, primarily through anchoring the plant in the soil, which provides stability against environmental factors such as wind and erosion. This anchorage is crucial for the plant’s upright growth and overall structure. Additionally, roots are responsible for the absorption of water and essential nutrients from the soil. These nutrients are critical for the plant's metabolic functions and overall health.

While other options mention important plant processes, they do not capture the core role of roots. Transporting water (as mentioned in another option) is a function closely associated with roots but does not encompass the anchoring function. Similarly, seed production and photosynthesis are functions performed by other plant parts, such as flowers and leaves, rather than roots. Therefore, the main functions of roots are indeed to anchor the plant securely while absorbing vital resources needed for growth.
