Answer 2

The stiffness of paddy straw occurs due to presence of - A) hard fibers

•Rice straw is a rice by-product produced formed when harvesting paddy or agricultural field where rice is grown.

•Rice straw finds its uses as fertilizer and feedstock.

•Hardness of paddy straw owes to presence of high cellulose content.

•Cellulose is found in cell walls to impart mechanical strength to them.

•Collenchyma are cells with thick walls, which provide additional strength to cells.

•Stone cells or sclereids have high content of lignified cells which provide great strength and hardness.

•Silica cells are found in epidermis of grass leaves.
