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.

2017年1月20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.

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.

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.

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.

2 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.

2019年6月7日 · An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane.

2022年7月24日 · In a strict definition, an organelle is a membrane -bound compartment or structure in a cell that performs a special function. In the less-stricter definition, an organelle refers to any cellular structure, whether it is membrane-bound or not, that carries a particular function.

The nucleus (sky blue) is a membrane-bound organelle found in eukaryotic cells that contains most of the cellular DNA. The DNA (not pictured) contains the information to create thousands of different proteins and RNAs that allow the cell to function and respond to its environment. To start this process, a temporary copy of the DNA recipe, called messenger RNA, is made.
