Question

A plant tissue, when stained, showed the presence of hemicellulose and pectin in cell wall of its cells. The tissue represents

• A. Collenchyma
• B. Sclerenchyma
• C. Xylem
• D. Meristem

Answer 1

The correct option is A Collenchyma

Collenchyma: Cells of collenchyma contain protoplasm and are living. Cells walls show localized thickenings due to deposition of cellulose, hemicellulose and pectin substances.

Sclerenchyma: Young cells are living but mature cells become dead due to deposition of impermeable secondary wall. Cell walls show uniform thickening of secondary wall due to deposition of lignin.

So, the correct answer is 'Collenchyma'.
