Correct answer
C. Coralloid roots of Cycas
Step-by-step solution
The coralloid root is developed in Cycas . It is produced in clusters at the base of the stem and protrudes out over the ground. It is dichotomously branched and greenish-brown in colour. It contains an algal zone in the cortex. This algal zone contains blue-green like Nostoc and Anabaena , which grow in symbiotic association with coralloid roots.
