Answer: The correct answer is-
To take in minerals form soil.
Roots are the significant organs of vascular plants that are located below the surface of soil.
They have specialized adaptation in their structures that enable them to absorb mineral ions ( such as sodium, potassium, phosphates, nitrates, magnesium that are very essential for plant growth) and water from the ground.
For instance, some plants possess fibrous roots that increase the surface area for absorption of minerals and other plants have tap root system ( that penetrates deep down to access water reservoirs) with lateral branches.
