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.Roots are usually the first part of the plant to emerge when a seed germinates. This tells us something about their importance in the life of a plant and the role they play. Roots have two main functions. First, they anchor the plant to the soil or compost in which the plant is growing.
Second, they take in water and minerals (sometimes referred to as salts) which are needed by all parts of the plants for growth. They also take in oxygen from the compost. Oxygen is as necessary to plants as it is to animals; like animals, plants breathe by taking in oxygen and giving off carbon dioxide.
Some roots have other important roles. One of these is to help in propagation; some plants can be increased from root cuttings, which are either placed on the surface of the compost and lightly covered, or inserted vertically into the compost.
Answer:
1) Absorption of water
2) storage of food and nutrients
3) conduction of absorbed water and nutrients to stem
4) vegetative reproduction and competition with other plants
5) soil binding
