Modification of Fibrous Roots
Fibrous roots are characterized by numerous thin roots that arise from the base of the stem. These roots are similar in girth and form a dense, interconnected network. These roots are typically found in monocots, such as grasses, lilies, and orchids.
Storage
Various plants, such as sweet potatoes, possess fibrous roots that undergo modification, transforming into storage roots. These specialized roots store carbohydrates, providing a valuable source of food and nutrition.
Pneumatophores
Root modifications in mangrove trees occur as fibrous roots may develop pneumatophores which are specialized structures that extend above the water surface to facilitate oxygen uptake in waterlogged soils.
Nitrogen Fixation
Despite having fibrous roots, some plants such as the white clover have the ability to form nodules. These nodules host nitrogen-fixing bacteria, which convert atmospheric nitrogen into a form fit for the plant therefore enhancing soil fertility.
Reproduction
In various plant species with a fibrous root system, buds develop on the roots. These buds play a role in vegetative propagation, wherein, under favorable conditions, they can develop into a separate new plant.
Root Modifications – Tap Root & Adventitious Roots
Modification of Roots is the process by which roots alter their shape to absorb and transport water and minerals from the soil to various parts of the plant. In addition, the function of roots includes absorbing water and minerals and transporting them to the stem, storing food, and providing support to the plant body. Root modifications emphasize a plant’s ability to survive. This article explains the modifications of roots, focusing on the modification of taproot and adventitious root systems.
