Aquatic plants have hydrophytic adaptations to survive in water. Submersion-adapted structures and features are included.
Aquatic plants have unique root systems for anchoring and nutrient absorption. Some have floating or adventitious roots above water.
Aerenchyma Tissues: Air passages in the plant structure allow oxygen to enter submerged tissues and discharge gasses created during underwater respiration.
Aquatic plants with buoyant leaves can maximize photosynthesis by floating on the water surface.
Air pockets: Some aquatic plants produce air pockets in their tissues to boost buoyancy and retain sections above water.
Some aquatic plants have submerged or decreased stomata to prevent excessive water loss.
Flexible Stems: Aquatic plants can bend and move with water currents, lessening water flow damage.
Rhizomes and Tubers: Water lilies use rhizomes or tubers to anchor and store nutrients to survive in variable water conditions.
