Question

Which tissue provides mechanical strength to plant?

• A. Sclerenchyma
• B. Parenchyma
• C. Chlorenchyma
• D. Both A and B
  

Answer 1

The correct option is A Sclerenchyma

• The ground tissue in plants that provide mechanical strength to the growing plants and plant parts are known as the sclerenchyma tissues (dead at maturity).
• The two types of sclerenchyma cells are- fibres and sclereids.
• These cells have intrusive growth.
• The cell walls are thickened (secondary wall) and are composed of cellulose, hemicelluloses and lignin.
• The rigidity of these tissues depends on the orientation of cellulose.
• So, the correct answer is 'Sclerenchyma'.
