8. What plant tissues are responsible for supporting of plant?

The supportive tissues of plants are collenchyma and sclerenchyma.

Collenchyma is made of elongated, living cells that accumulate cellulose and pectin in some regions of the cell wall,giving them an unequal thickness and thus providing flexibility.

Sclerenchyma mostly consists of dead cells killed by lignin deposits (lignin is an impermeable biopolymer), which form elongated, rigid and impermeable fibers. Sclerenchyma is a plant tissue widely used in the textile industry.
