Combo of a root and stemEx: Beets, carrots, turnips, radishes
Propagative Roots
Buds on roots develop into aerial stems (suckers). Fruit trees and some invasive plants spread this way.
Pneumataphores
Spongy roots that extend above the water's surface and enhance gas exchange. Found in mangroves.
Aerial Roots
Roots that extend above ground & take in moisture from the air.
Parasitic Roots
No chlorophyll and dependent on chlorophyll-bearing plants for nutrition.Ex: Dodder plants and mistletoes with haustoria
Adventitious Roots
Develop from another stem or leaf. Ex: aerial roots of air plants, pneumatophores, or haustoria
Mycorrhizae
Fungi roots, more than 95% of land plants have these. Mostly mutualistic symbiosis, greatly increase the surface area for absorption. Enhance the uptake of mainly phosphorous.
Root Nodules
Fix nitrogenous compound, found on legumes. Infected with rhizobium bacteria. Ex: peas, beans, alfafa
