Which statement best describes the role of roots in soil?

• A. Photosynthesis in roots
• B. Water transport only through leaves
• C. Seed production
• D. Anchorage of the plant in the soil

Answer: (D)

Roots primarily provide anchorage in the soil, securing the plant so the shoots can grow upright and resist wind and gravity. This stability is essential for the plant to access light and develop above-ground structures. While roots do take up water and minerals and can store some nutrients, their defining role in soil is to anchor the plant. Photosynthesis mainly happens in the leaves, and seed production occurs in flowers and fruits, not roots. Water movement involves the whole plant, with roots absorbing water and xylem transporting it upward to the leaves.
