How does cellulose, hemicellulose, and pectin impact the direction of cell growth?

Homework Answers

Answer #1

Plant cell is generally composed of many complex molecules and include cellulose, hemicellulose and pectin.

They are present in different proportions. Plant cells are structurally strong and rigid.

Xyloglucan,the most abundant hemicellulose forms hydrogen bonds along the cellulose microfibrils and crosslinks

between cellulose microfibrils. The xyloglucan indirectly connects cellulose using network of pectin polymers.

They form a network of interconnected web and supports and gives strength to plant cell.
