The cell wall not only serves as an exoskeleton encasing plant cells, but it also directs cell expansion polarity (Wolf et al., 2012; Du and Jiao, 2020). Among cell wall polymers, cellulose microfibrils and their orientation are the major determinants of cell morphogenesis (Keegstra et al., 1973; Cosgrove, 2001, 2018; Hofhuis et al., 2016).

Aug 10, 2016 · Introduction. The plant cell wall is a complex structure that fulfills a diverse array of functions throughout the plant lifecycle. In addition to maintaining structural integrity by resisting internal hydrostatic pressures, the cell wall provides flexibility to support cell division, a biochemical scaffold that enables differentiation, and a pathological and environmental barrier that defends ...

Sep 11, 2017 · Plant cell walls consist primarily of carbohydrates and phenolic compounds ( Figure 2 ), with only minor amounts of structural proteins (up to 10%), a composition optimal for photosynthetic organisms, which have access to abundant C-sources, but with often limited access to nitrogen and sulphur present in proteins.

The Plant Cell Wall. The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant. It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time. The walls of neighboring plant cells, cemented together to form the intact ...

Jun 28, 2024 · All cell walls contain two layers, the middle lamella and the primary cell wall, and many cells produce an additional layer, called the secondary wall. The middle lamella serves as a cementing layer between the primary walls of adjacent cells. The primary wall is the cellulose -containing layer laid down by cells that are dividing and growing.
