Will mark brainliest for best answer what is the name of the polysaccharides that makes up plant cell walls?

In the primary (growing) plant cell wall, the major carbohydrates are cellulose, hemicellulose and pectin. The cellulose microfibrils are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix.

I hope this helps.
