A scientist is studying a newly discovered plant species. Microscopic analysis of the stem reveals living cells with unevenly thickened cell walls, primarily composed of pectin and hemicellulose, providing flexible support. These cells lack lignin and are found in patches beneath the epidermis. Which tissue type is being observed?
Collenchyma
Sclerenchyma
Parenchyma
Xylem
Which of the following characteristics is NOT typical of collenchyma cells?
Uniformly thickened cell walls
Presence of pectin in the cell wall
Living at maturity

The flexibility of collenchyma tissue is primarily attributed to:
The presence of lignin in the cell wall
The thin cell walls
