Cells are structural and functional “building block of life”. The word cell, from “cella” the Latin for small room, was adopted by English scientist Robert Hooke to describe what he saw through a microscope.
The classi cell theory was developed by Matthias Jakob Schleiden, Theodor Schwann and Rudolf Virchow.
1. All living organisms are made up of one or more cells.
2. Cells are the basic unit of life.
3. All cells arise from pre-existing cells.
4. The cell is the unit of structure, physiology, and organization in living things.
5. The cell retains a dual existence as a distinct entity and a building block in the construction of organisns.
Cell biology studies how the cell works in specialized functions like reproduction and tissue formation. Cell biologists want to know how healthy cells carry out their jobs, and how disease affects cells.
Cell biology draws heavily on genetics to research such things as human and animal cloning, how cells recognize each other during the immune response, how cancerous cells are formed, and how cells can be used to make useful products.
Cell biologists have learned how to transform fat cells into cartilage cells, which are used to replace injured tissue in joints.

Mitochondria, a membrane-enclosed organelle found in most eukaryotic cells, generate most of the cell's adenosine triphosphate (ATP) and play an important part in metabolic tasks.
Mitochondria have slightly different DNA and appears to be transmitted in the egg only, thus giving us important information about our evolutionary history.
The word mitochondrion comes from the Greek mitos=thread + khondrian=granule.

Anthrax, one of the oldest recorded diseases, is caused by the bacterium Bacillus anthracis. The word anthrax is from the Greek word for coal, in reference to the black skin lesions victims develop in a cutaneous skin infection. Anthrax is highly lethal in some forms and is capable of forming long lived spores. German researcher Robert Koch isolated the Bacillus anthracis in 1877, French scientist Louis Pasteur developed the first effective vaccine for anthrax in 1881.

Cancer is a group of diseases in which cells grow and divide without respect to normal limits, invade and destroy adjacent tissues, and/or spread to other locations in the body (metastatize).

Diatoms, one of the most common types of phytoplankton, usually consist of two asymmetrical sides with a split between them, hence the group name (Greek dia=through + temnein=to cut, i.e. cut in half).
The silica cell wall (frustule) show a wide variety of form in diatoms, some quite beautiful. Diatom fossil evidence suggests that they originated during, or before, the early Jurassic Period.
