Comparison between Normal and Coralloid Root:

 

Normal root:	Coralloid root:
1. Develops from the radicle, tap root system   2. Geotropic   3. Such characters are absent   4. Such infection is absent     5. Root hairs are present   6. Cortex is smaller   7. Such division is absent       8. Secondary growth present   9. Main functions are: fixation of plant, absorption of water and mineral nutrients	1. Develops from the normal roots   2. Apogeotropic   3. Develops from the normal roots   4. Dichotomously branched and appears like coral   5. Gets infected with algae, bacteria   6. Cortex is wider in comparison   7. Due to presence of the algal zone in the cortex, it is differentiated into outer cortex and inner cortex   8. Xylem very little or absent   9. Main function is nitrogen fixation
