     Sclerenchyma are dead mechanical tissue whose cells are long or short, narrow, thick walled and lignified. It acts as a versatile mechanical tissue that provides maximum mechanical strength to the plant. While, the      other tissue such as parenchyma helps in storage of food and water and is involved in activities like photosynthesis, respiration, etc. Collenchyma  is   responsible  for  performing photosynthesis due to the presence of chloroplast and aerenchyma is responsible for allowing exchange of gases between the shoot and the root.
