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.

2019年10月4日 · The term organelle is derived from the word ‘organ’ and refers to compartments within the cell that perform a specific function. These compartments are usually isolated from the rest of the cytoplasm through intracellular membranes.

2023年12月26日 · An organelle is a compartment within a eukaryotic cell that has a specific function. The name “organelle” comes from the idea that these structures are to cells what an organ is to the body. Typically, organelles are enclosed within their own lipid bilayers.

2024年3月5日 · Cell organelles are specialized structures found within eukaryotic and prokaryotic cells that perform specific functions necessary for the survival and proper functioning of the cell.

2025年1月24日 · Organelle, any of the specialized structures within a cell that perform a specific function (e.g., mitochondria, ribosomes, endoplasmic reticulum). Organelles in unicellular organisms are the equivalent of organs in multicellular organisms.

There are various organelles present within the cell and are classified into three categories based on the presence or absence of membrane. Organelles without membrane: The Cell wall, Ribosomes, and Cytoskeleton are non-membrane-bound cell organelles. They are present both in the prokaryotic cell and the eukaryotic cell.

2024年10月11日 · Dive into cell organelles: definitions, key structures, and vital functions. Explore how each organelle powers essential cellular processes.

3 天之前 · An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

2023年10月12日 · An organelle is a membrane-bound structure found within a eukaryotic cell. It is similar to an organ in an animal body. There are many cell organelles in a cell, each having a distinct structure and specific functions. Some are without membrane, while others are either single or double-membrane-bound.

5 天之前 · An organelle is a specialized structure within a cell. It performs specific functions necessary for the cell’s survival and operation. How Do Organelles Function In Cells? Organelles function by carrying out specific tasks. These tasks include energy production, protein synthesis, and waste removal.
