List out the anatomical adaptations of hydrophytes.

Anatomical characters of the hydrophytes are

• Cuticle is absent or present as thin layer.
• The epidermis contains thin-walled cells and helps in absorption of water.
• Stomata are absent in submerged plants and absorption of gases through diffusion by the thin-walled cells.
• Aerenchyma is present.
