Question

Coralloid roots help the plant

• A. Absorb water more efficiently
• B. Absorb and fix nitrogen better
• C. Anchorage to the soil
• D. Respiration

Answer 1

Answer: (B)

Absorb and fix nitrogen better

The coralloid roots contain symbiotic cyanobacteria (blue-green algae), which fix nitrogen and, in association with root tissues, produce such beneficial amino acids as asparagine and citrulline.
Pneumatophores help in better absorption of air or respiration and hence called as breathing roots.
