Importance of Modifications of Plant Roots
Modifications of Roots is an essential adaptation technique that helps in processes like nutrient absorption, water uptake, anchorage, protection, and reproduction.
- Nutrient Absorption: Various plant species form symbiotic relationships with mycorrhizal fungi, which help in nutrient absorption from the soil, particularly enhancing the uptake of phosphorus and nitrogen.
- Water Uptake: The plants that grow in waterlogged soils or marshy environments develop aerenchyma (soft plant tissue that consists of air spaces), which helps in the exchange of gases and improves oxygen uptake for roots.
- Anchorage: Modifications like prop and buttress roots provide anchorage to the plant i.e. it provides the plant with additional support, specifically in regions with poor soil or extreme weather conditions.
- Reproduction: In various fibrous-rooted plants, roots develop buds that give rise to new plants, helping in reproduction and spreading.
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.
