• Sometimes roots get modified to perform different functions like Storage of food, respiration, climbing, etc.
• These types of roots are called modified roots.

Explanation-

• The Coralloid roots are the specialized roots found in cycas, these roots exhibit a symbiotic relationship between the cyanobacteria and cycas where the cyanobacteria fix the nitrogen and in return, the cycas provide a stable environment to live.
• Cycas, a genus of 105 species of palmlike tropical and subtropical ornamental cycads (family Cycadaceae), among them trees 12 meters (40 feet) or more in height. 
• Their leaves are dark green and circinate (uncoiling as fern leaves do), differing from those of other members of the family in having a midrib but no lateral veins. 
• The seeds are borne along the margins of modified leaves, which are arranged in a whorl at the top of the trunk, rather than in compact cones. 

Thereby coralloid roots are found in cycas.
