what are the different functions of roots?

For nutrition, plants like dodder have specialized roots called parasitic roots arising from their stem, which help them to absorb water and nutrients from the host. Their formation is basically a survival mechanism, and therefore, their primary duty is to supplement the main root when its functioning is impaired due to disease, damage, or otherwise.
