Which of the following plants belong to a single group?
Show answer Hide answer
Answer: B. Rhizophora and Avicennia
Explanation
Rhizophora and Avicennia both belong to the same ecological and taxonomic group of mangrove plants. These genera share specialized morphological adaptations enabling survival in saline coastal intertidal zones. Grouping them together reflects their classification within true mangrove vegetation communities. Mangroves are salt-tolerant halophytic trees thriving in muddy, oxygen-poor tropical coastal tidal areas. Avicennia species develop pneumatophores for root aeration while Rhizophora species feature stilt roots. Coastal intertidal zones present extreme osmotic challenges that restrict most non-halophytic plant species.
Mangrove forests protect tropical shorelines from severe storm surges and coastal erosion effectively. Conservationists prioritize protecting Rhizophora and Avicennia habitats to preserve marine nursery grounds. Ecological restoration projects along tropical estuaries frequently replant mangrove species to restore coastlines. Option A pairs Mangifera with Rhizophora combining inland fruit trees with coastal mangroves incorrectly. Option C combines Rhizophora with Balanophora which is a parasitic root plant unrelated to mangroves. Option D groups Avicennia with Balanophora ignoring the parasitic nature of Balanophora species.
