Answer 2

Coralloid root:

The roots which contain symbiotic cyanobacteria or blue-green algae which fix the nitrogen with the help of the root tissue and produce amino acids like asparagine and citrulline.

Differences between the normal root and coralloid root:

Normal roots are roots which grow deep in the soil and have root branches and possess root hairs and geotropic in nature.

Normal plants have this type of normal roots but some plants have coralloid roots like Cycas.
