Modifications of Root
Plant roots display modifications which enable them to carry out purposes beyond water absorption and anchoring. These modifications occur in the form of adaptations to the environment. For food storage purpose, the roots are modified in case of carrots and sweet potatoes. In plants that are present in swamps, many roots come out upward from the ground. These are empty roots, called pneumatophores. Their function involves the exchange of gases in the roots.
Root System in Plants – Types and Functions of Root
The Root System in Plants is an intricate network of structures that allows the transport of nutrients and water. A root is a piece of a vascular plant typically present under the ground. Its essential functions include ingestion of water and disintegrated minerals, conduction of these to the stem, and capacity to hold food varieties. The root is different from the stem as it lacks leaf scars and buds, has a root cap, and has branches that start from the inner tissue instead of buds.
Taproot and Fibrous Roots are the two major Types of Roots. The taproot is found deep in the soil and the fibrous root remains shallow. The roots function as an anchor and also help absorb minerals and nutrients from the soil.
