Plant cell wall. Coloured scanning electron micrograph (SEM) of cellulose microfibrils (strands) in a plant cell wall. Unlike animal cells,plants cells are enclosed in a protective rigid cell wall. The main constituent of the wall is cellulose,a complex polysaccharide that forms microfibrils. Two other polysaccharides,pectin and glycan,cross-link with the cellulose to increase the strength of the cell wall. Cellulose microfibrils measure between 5 nanometres and 15 nanometres in diameter | |
