Web23 Jul 2024 · In plants, there are three parts of cell walls: (1) primary cell wall, (2) secondary cell wall, and (3) middle lamella. The primary cell wall is a thin, flexible and extensible layer of the cell wall composed of cellulose, pectin, and hemicellulose (especially, xyloglucan). The primary cell wall contains more pectin than the secondary cell wall. WebMediated by stem cell-like (meristematic) tissues, in this case predominantly the cambium (Figure 1b, c), lateral growth of stems and roots is essential for generating large plant bodies. Thereby, it substantially contributes to the dominance of seed plants in terrestrial ecosystems, to wood formation and thus to carbon immobilization.
