Basic structure of a peroxisome Distribution of peroxisomes (white) in HEK 293 cells during mitosis Peroxisome in rat neonatal cardiomyocyte. A peroxisome (IPA: [pɛɜˈɹɒksɪˌsoʊm]) [1] is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells. [2] [3] Peroxisomes are oxidative organelles.
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 small unique structures of a cell that perform specialized tasks. They are often suspended in the cytosol , or attached to the plasma membrane . Organelles were historically identified through the use of some form of microscopy and by cell fractionation .
The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells [13] All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. [14] The activity of an organism depends on the total activity of independent ...
A cell's ability to vitrify in the absence of metabolic activity, as in dormant periods, may be beneficial as a defense strategy. A solid glass cytoplasm would freeze subcellular structures in place, preventing damage, while allowing the transmission of tiny proteins and metabolites, helping to kickstart growth upon the cell's revival from ...

A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi.Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.
