From: The impact of alterations in lignin deposition on cellulose organization of the plant cell wall
The microfibril angle increases from the periphery of the stem to the center, reflecting a change in the way cellulose fibrils coil around cells. Microfibril angle is the greatest in regions of lowest oriented fibril content as can be seen in the plots in the upper left. The grid within the optical image shows the region scanned and identifies positions with fibril orientation corresponding approximately to the diagrams at the bottom of the figure
