When we keep some gram seeds wrapped in moist cotton they germinate after 3 to 4 days. It is difficult to separate them from the cotton.what primary function of the root does this show?

The difficulty in separating the germinated gram seeds from the moist cotton highlights the primary function of the root, which is to anchor the plant and absorb water and nutrients from the soil. As the roots develop, they spread out and entangle with the cotton fibers, demonstrating their role in establishing a stable connection to a growing medium. This process also emphasizes the importance of roots in supporting the plant's overall growth and development.
