Question

Which of the following substances is absent in the cell walls of sclerenchyma?

• A. Cellulose
• B. Pectin
• C. Lignin
• D. Hemicellulose

Answer 1

The correct option is B Pectin

• The sclerenchyma tissue has rectangular-shaped cells. These cells are without a nucleus and protoplasm. They show greater deposition of lignin in the walls resulting in uneven thickness and are referred to as the dead cells.
• Cellulose and hemicellulose are also present in the sclerenchyma wall. Pectin is present in soft plant tissues and absent in sclerenchyma.

Thus, the correct answer is option B.
