This intriguing question comes from Flowering Plants Morphology topic in division Morphology of Flowering Plants of Biology – Class 11

Answer 1

Correct choice is (d) Plants that grow tall derive their additional mechanical support by sending pillar like woody roots called stilt roots

Easy explanation: Root system helps in absorption of water and minerals from soil. In plants like mangroves, breathing roots called pneumatophores are present. Pneumatophores grow vertically upwards and exchange gases through lenticels. Plants that grow tall derive their additional mechanical support by sending pillar like woody roots called prop roots.
