It is the small fiberous roots that get the nutrients and water from the soil, the larger roots are mainly for transporting the nutrients and water up to the tree. Each of the roots is responsible for a certain part of the tree. So if you were to cut off some roots, only the parts of the tree that they served would be affected.
they provide nutrition, as they are edible
what would happen to plants nutrition if plants did not have roots
Legumes contain nitrogen fixing bacteria in their roots, which provides nutrients to other plants. Nutrition
Neutralisation is the process that occurs in plant roots. The plant roots provide nutrition for the plant such as carrying minerals and water up to the other plant section (leafs, petals, buds, etc.)
The mode of nutrition for Kingdom Plantae Is mostly photosynthesis and also when the roots of the plant absorbs nutrients from the soil.
Bromeliads primarily obtain their nutrition from organic matter that accumulates in the central cup of their leaves. They can also absorb nutrients through their roots from decaying plant material in the surrounding soil. Additionally, some species have developed a mutualistic relationship with insects that provide them with additional nutrients through their waste.
To propagate a Calathea plant effectively, you can divide the plant at the roots during repotting, ensuring each new section has roots attached. Plant the divisions in fresh soil, keep them moist but not waterlogged, and provide indirect light. This method helps the plant establish new roots and grow successfully.
Roots anchor the tree in the ground and support it, and provide the nutrients required for life.

The roots provide the life source to the tree , so, cut the roots, kill the tree.
Banyan trees have prop roots to provide extra support for their spreading branches. The prop roots grow from the branches and extend downwards to the ground, forming a strong network that helps the tree stay upright and stable. This unique adaptation allows banyan trees to grow to immense sizes and live for hundreds of years.
Buttress Roots provide extra support for trees growing in spongy wet soils.
