Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. [1] ...
The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
Cell culture in a small Petri dish Epithelial cells in culture, stained for keratin (red) and DNA (green). Cell culture or tissue culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment.
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.

Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
The ultrastructure of a single bacterial cell (Bacillus subtilis).The scale bar is 200 nm.. Ultrastructure (or ultra-structure) is the architecture of cells and biomaterials that is visible at higher magnifications than found on a standard optical light microscope.
The term cell group is derived from biology: the cell is the basic unit of life in a body. In a metaphorical sense, just as a body is made up of many cells that give it life, the cell church is made of cell groups that give it life.
The wolverine's questionable reputation as an insatiable glutton (reflected in its Latin genus name Gulo, meaning "glutton") may be in part due to a false etymology.The less common name for the animal in Norwegian, fjellfross, meaning "mountain cat", is thought to have worked its way into German as Vielfraß, [5] which means "glutton" (literally "devours much").
