Unusual names have caused issues for scientists explaining genetic diseases to lay-people, such as when an individual is affected by a gene with an offensive or insensitive name. [14] This has particularly been noted in patients with a defect in the sonic hedgehog gene pathway and the disease formerly named CATCH22 for "cardiac anomaly, T-cell ...
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 .
On 2021, Stephen Quake guessed that the upper limit of the number of human cell types would be around 6000, based on a reasoning that "if biologists had discovered only 5% of cell types in the human body, then the upper limit of cell types to discover is somewhere around 6000 (i.e., 300/0.05)." [10] Other different efforts have used different ...

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 ] Animal cells , plant cells and microorganism cells show similarities in their functions even though they vary in structure.
