Question: what is difference between parenchyma collenchyma and sclerenchyma?
Answer: Parenchyma cells are found in all organs of the plant, seeds, fruits, flowers, leaves, stems and roots. Collenchyma cells consist of unevenly thick cell walls. They contain vacuolated protoplasts and are absent in monocots. Sclerenchyma cells are dead cells at their maturity, containing the thickest cell walls.
