Mitochondria definition
Definition of MITOCHONDRION. : any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes — see cell illustration.— mi·to·chon·dri·al \-drē-əl\ adjective. any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes — see cell illustration. — mi·to·chon·dri·al \-drē-əl\ adjective.

The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek μίτος, mitos, i.e. thread, and χονδρίον, chondrion, i.e. granule or grain-like.Mitochondria range from 0.5 to 1.0 μm in diameter.A considerable variation can be seen in the structure and size of this organelle. Unless specifically stained, they are not visible.he word mitochondrion comes from the Greek μίτος, mitos, i.e. thread, and χονδρίον, chondrion, i.e. granule or grain-like.

Mitochondria: Structures located in the cell's cytoplasm outside the nucleus. Mitochondria are responsible for energy production. Each consists of two sets of membranes: a smooth, continuous outer coat and an inner membrane arranged in tubules or in folds that form plate-like double membranes (cristae).The mitochrondria are the principal energy source of the cell.itochondria are responsible for energy production. Each consists of two sets of membranes: a smooth, continuous outer coat and an inner membrane arranged in tubules or in folds that form plate-like double membranes (cristae). Definition. noun, singular: mitochondrion. Spherical or rod-shaped organelles found within the cytoplasm of eukaryotic cells, and are referred to as the “powerhouse of the cell since they act as the site for the production of high-energy compounds (e.g. ATP), which are vital energy source for several cellular processes.hat is, they are capable of using glucose and oxygen to produce energy (and releasing carbon dioxide and water in the process) for use in many metabolic processes. Thus, it is not surprising to find several mitochondria in high energy-requiring cells, such as muscle cells. The number of mitochondria in a cell can vary widely by organism, tissue, and cell type. For instance, red blood cells have no mitochondria, whereas liver cells can have more than 2000. The organelle is composed of compartments that carry out specialized functions.he word mitochondrion comes from the Greek μίτος, mitos, i.e. thread, and χονδρίον, chondrion, i.e. granule or grain-like.

They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.Many of the reactions involved in cellular respiration happen in the mitochondria. Mitochondria are the working organelles that keep the cell full of energy.Mitochondria are small organelles floating free throughout the cell.he biochemical processes of the cell are known as cellular respiration.

The mitochondria are now double-membraned organelles that exist within a eukaryotic cell's cytoplasm, the types of cells that make up our body.

The cytoplasm is gel-like and located inside a cell's plasma membrane but outside of the nucleus. Mitochondria are well-defined cytoplasmic organelles of the cell which take part in a variety of cellular metabolic functions. Survival of the cells requires energy to perform different functions.itochondria is a membrane bound cellular structure and is found in most of the eukaryotic cells.
