Verified

The plant supporting tissues are the collenchyma and sclerenchyma. The collenchyma is made of the elongated and living cells which accumulate cellulose and pectin in some regions of cell wall making them unequally thick and therefore providing flexibility.

The sclerenchyma is made mostly of the dead cells killed by the lignin deposition (lignin is an impermeable biopolymer) forming elongated, impermeable and rigid fibers. The sclerenchyma is a plant tissue widely used in textile industry.
