ROOT AND SHOOT SYSTEM

The Root System

The entire lower part of growing plants that is normally under the soil makes up the root system. Roots are branching organs which grow vertically into the soil. Roots have no leaves, nodes or buds.

In general, the plant root system consists of a taproot (primary root) or fibrous roots (adventitious roots), with attached branch roots and finer rootlets having root hairs close to the tip.
