Simple definition of organelle

In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. Organelles are either separately enclosed within their own lipid bilayers (also called membrane-bound organelles) or are spatially distinct functional units without a surrounding lipid bilayer (non-membrane bound orga… Webb30 mars 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.
