Web19 mei 2014 · Even though the histories of the two terms - stem cell and meristem - are separate , it is tempting to draw a parallel between meristematic cells in plants and adult stem cells in animals. In fact, it can be argued that the described concepts of stem cell, stem cell niche, and transit cell could be matched by specific cell populations within … WebMeristem. Meristem is a kind of tissue that mostly is present in plants. The meristematic cells undergo cell division; they can also form organs and tissues of certain types of plants. The cells that are differentiated do not have the ability to divide and form any cells, whereas the undifferentiated cells can undergo cell division.

WebThe meristematic tissue is mainly composed of a specific type of cells that have the function of dividing to synthesize fresh cells.

Web30 mrt. 2024 · Delineating quiescence and dormancy. Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations.
