Calculation of Number of Particles per Unit Cell of a Cubic Crystal System. Keeping the following points in mind we can calculate the number of atoms in a unit cell. An atom at the corner is shared by eight unit cells. Hence an atom ..

Generally, in the body of multicellular animals, we can recognize three types of cells: Undifferentiated cells Differentiated cells and Dedifferentiated cells..

Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory states that All living organisms a..

The history of the discovery of cells dates back to the 17 th century and is closely associated with the history of the invention of microscopes. An Italian microscopist Marcello Malpighi studied the structure of some plants and proposed the idea that plants are composed of tiny st..

Each cell can be regarded as a compartment by itself since it is bound on all the sides by a cell membrane. It separates the protoplasm within the cell from the surrounding environment. As a result, the cell is able to retain specific molecules and carry out ..
