Grasses have hollow jointed stems.Grasses belong to family Poaceae. e.g. Triticum vulgare and Oryza sativa.Possession of hollow jointed stems is a specific character of grasses as in wheat and rice. These hollow stems help in providing O2 to roots for respirationspecifically in rice that grows in water. Impregnation of cell walls with silica makes cells rigid and rough and supports the plant.

What makes the inside of a horsetail scratchy?
It's the silica crystals that make horsetail fern (Equisetum hyemale) a scratchy tool.Specifically, the plant forms silica crystals on the cell walls of its stems and branches. The crystals form in response to the drying of the plant's parts. It is the persistence of these crystals in the branches and stems that make the plant a scouring tool, in many places and throughout many time periods.
