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. WebHere, we will examine each. Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension. Microtubules are found in the interior of the cell where they maintain cell shape by resisting compressive forces. Intermediate filaments are found throughout the cell and hold organelles in place.
