The correct answer is Cellulose and Pectin.

• Collenchyma, in plants, supports tissue of living elongated cells with irregular cell walls.
  • Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross-section.
  • The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells.
