short answer:
two main purpose of roots are to deliver water and nutrients to the plant or tree and provide an anchor that keeps the plant or tree in the soil. Roots are generally the first part of any plant that emerges during germination.
full answer:
Roots should not be confused with stems, since roots grow down below the surface while stems grow up above the surface. Roots do not bear buds or leaves like stems do, although they do have fine hair-like structures that work to absorb minerals and water. Water passes up through the tiny root hairs and into the plant's vascular system. The process by which the water moves through the roots is called osmosis, and it can only occur when there is water inside the plant in a concentration that is higher than the surrounding soil or compost. If there's too much water in the soil, it has the opposite effect on a plant's roots in that it will cause water to be leached from the roots instead of taking water up into the root.
Notably, storage roots from certain plants like the carrot end up being eaten by humans. Other storage roots become tubers and rhizomes, like irises and dahlias
The purpose of a root of a plant is to not only absorb water and nutrients for the plant but also to anchor the plant in soil.
Tap root and the main root
it holds the plant in place and provides essential support for the plant to survive.
Tap root and Adventitious roots
soft flexible woody stiff
The root system of most plants is located underground in the soil. The main purpose of the root system is to anchor the plant and absorb water and nutrients from the soil to support growth and development.
The aim and the purpose.
The root system and the shoot system
Yes, it is. A tap root has a main root and roots spout out from the main root. The carrot itself is the main root and the root hairs are the supposingly "small roots".
The two main organ systems in plants are the shoot system and the root system.
A fibrous root system is the opposite of the tap root system (one main root).
