Why do some plants have aerial roots?

Aerial roots help plants survive in environments where traditional root systems may not function effectively. In tropical rainforests, epiphytes like orchids use aerial roots to absorb moisture and nutrients from the air. Mangroves use aerial roots, such as pneumatophores, to access oxygen in waterlogged soils. Climbing plants like ivy use aerial roots to anchor themselves to surfaces. These specialised roots demonstrate the incredible adaptability of plants to diverse habitats.
