Solution

Aerenchyma:

  1. Large air gaps exist in the parenchyma of aquatic plants to let them float on water.
  2. Such a parenchyma type is called aerenchyma.
  3. It is a type of tissue with air gaps. It gives hydrophytes buoyancy, allowing them to float to the water's upper surface.
  4. The buoyancy of floating plants is helped by aerenchyma.
  5. It helps in the respiration of aquatic plants and ensures that they get enough oxygen.

Final Answer: Aerenchyma tissue is present in aquatic plants that gives buoyancy and helps them to float in water.
