WebAug 16, 2024 · The meristematic region is the location of cell division, which means this is where new cells are made. The new cells then move into the elongation region in order to increase in size.
WebAug 4, 2024 · Where is the meristematic zone located in a root? MERISTEMATIC ZONE OF A ROOT. The meristematic zone of a root is also known as its growing point. It is about 1mm in length. It is located partially within and partially behind the root cap in the sub-apical region. The cells in this zone show prominent nucleus and dense cytoplasm. WebThe cells in this region are rich in protoplasm, possess large conspicuous nuclei. Their cell walls are primary in nature, thin and cellulosic with abundant plasmodesmata connections. The cells proximal (just next, away from the tip) to the meristematic zone represent the phase of elongation.
WebLater on, opposite to the root meristem, a cell mass differentiates giving the shoot apical meristem. The primary shoot meristem is a part of a complex organization of the shoot apex arranged in three zones (Figure 5B): (1) the central zone harbors slowly dividing stem cells at the summit and an organizing center beneath maintaining the stem cells, (2) all … WebWhen a meristematic cell divides in two, the new cell that remains in the meristem is called an initial, the other the derivative. As new cells are added by repeated mitotic divisions. These types of tissues are generally found …
