The CELL THEORY‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have

Sep. 21‚ 2014 Stem Cells Stem cells are the beginning of organism creation and have the potential to separate‚ becoming any kind of organism‚ endlessly. These cells have not gone through the process known as differentiation‚ which gives the cell a specific function.

There are multiple stem cells that have been determined

Description of Probiotics Probiotics are living microscopic organisms‚ or microorganisms‚ that scientific research has shown to benefit the health. Most often they are bacteria‚ but they may also be other organisms such as yeasts. In some cases they are similar‚ or the same‚ as the “good” bacteria already in the body‚ particularly those in the gut. These good bacteria are part of the trillions of microorganisms that inhabit the bodies. This community of microorganisms is called the microbiota.
