- Organelles are specialized membrane-enclosed structures in the cytoplasm of eukaryotic cells. The nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle. The nuclear envelope is connected to a system of membranes in the; cytoplasm called the endoplasmic reticulum (ER).

organelles defintions (3) A sphere-shaped structure found in the cytoplasm of prokaryotic and eukaryotic cells. Some ribosomes occur freely in the cytosol whereas others are attached to the nuclear membrane or to the endoplasmic reticulum (ER) giving the latter a rough appearance, hence, the name rough ER or rER.

What Is An Organelle An organelle is a specialized part of the cell that serves a specific purpose within the cell. There are many organelles present within a cell and they also vary depending on what kind of cell we are talking about, whether it be a plant or animal cell. Here are a few of the organelles and their functions: 1  nucleus-this would be like the brain of the cell and gives direction to the rest of the cell. 2  cell membrane-this provides protection for the cell and allows material to enter and leave the cell. 3  vacuoles-these are used for storage of materials such as water.

Organelle In cell biology, an organelle (/ɔːrɡəˈnɛl/) is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers. The name organelle comes from the idea that these structures are to cells what an organ is to the body (hence the name organelle, the suffix -elle being a diminutive). Organelles are identified by microscopy, and can also be purified by cell fractionation.

Lysosome A lysosome (derived from the Greek words lysis, meaning to loosen, and soma, body) is a membrane-bound cell organelle found in most animal cells (they are absent in red blood cells).nzymes of the lysosomes are synthesised in the rough endoplasmic reticulum. The enzymes are released from Golgi apparatus in small vesicles which ultimately fuse with acidic vesicles called endosomes, thus becoming full lysosomes.
