Question

List a few adaptations found in submerged hydrophytes.

Answer 1

1. Thin, soft, spongy stem with air cavities (aerenchyma) for buoyancy.
2. Thin, narrow, ribbon-like leaves offering least resistance to water.
3. Poorly developed root system; root hairs and root caps are absent.
4. Reduced or absent cuticle and stomata, allowing gas exchange and absorption directly from water.
