Column I	Column II
A. Parenchyma	Thin walled, packing
B. Photosynthesis	cells Carbon fixation
C. Aerenchyma	Localised thickenings
D. Collenchyma tissue	Buoyancy
E. Permanent tissue	Sclerenchyma

Answer:

  The correct matching is

Column I	Column II
A. Parenchyma	Thin walled, packing
B. Photosynthesis	cells Carbon fixation
C. Aerenchyma	Buoyancy Localised
D. Collenchyma	thickeninos
E. Permanent tissue	Sclerenchyma

  Parenchyma are thin wailed cells found in soft parts of the plant. In hydrophytes such as water hyacinth, Hydrilla etc., large air cavities are present in parenchyma to give buoyancy to plant, Such type of parenchyma is called aerenchyma.
