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 organ… Witryna8 lut 2024 · Abstract. C. merolae cells contain four types of single-membrane-bound organelles—the ER, Golgi bodies, vacuoles/lysosomes, and peroxisomes—the dynamics of which have been studied during the cell cycle by fluorescence microscopy and electron microscopy.
