Many different environmental conditions often have an effect on how plant roots are shaped, sized, and grow. Roots very commonly store nutrients such as starch. They provide for a safe subterranean storage component. Roots can also hold the plant into the ground and can adapt to be heavily intertwined and stable in windy conditions. Some roots like those of poison ivy will form in such a way that the plant will be able to “climb” and grow along an adjacent structure. A “taproot system” and “fibrous root system” are two of the main types of modified roots. A taproot system will have single major root with several roots branching off of it. On the other hand, a fibrous root system will have many small intertwining roots. Another example of a modified root is an aerial root. These roots grow outside of the ground and are thickly coated to prevent water loss from evaporation. Several other types of modified roots include buttress roots, water storage roots, pneumatophores, parasitic roots, and contractile roots. In the image above, we can see a modified taproot system with aerial root components.
