The two main functions 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.Continue Reading
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.Learn more about Botany
The two main types of root systems are taproots and fibrous roots. A taproot consists of a single large, central root with smaller side roots, while fibrous root systems consist of networks of many small roots.Full Answer >
Grassland decomposers are organisms that feed on decaying organic matter, breaking it down into nutrients that are returned to the soil for more plant growth. These decomposers are insects, fungi and microorganisms.Full Answer >
Xylem is a type of vascular tissue that is responsible for moving water through a plant from its roots to its leaves. Columns of xylem tissue begin in the root hairs and rise all the way up through the leaves of a plant.Full Answer >
Plant growth is caused by water that is absorbed by the plant's roots and sunlight that spurs photosynthesis, which is the process of creating food for the plant. Plants also need space, time, clean air, healthy soil and nutrients to grow. The main ingredients that plants need are phosphorous, nitrogen and potassium.Full Answer >
