project report on types of unit cells+solid stse

Types of Unit Cells - There are three types of non-primitive unit cells. Taking the example of a cubic unit cell we can see that there are three types. They are: fig 2.2 - Types of unit ..

Face centred cubic The particles are present not only at the corners but also at the centre of each face of the unit cell..

Cell division is a method by which new cells are originated from pre-existing cells. The formation of daughter amoebae in amoeba, the development of sex cells and the growth of a young animal or plant into an adult, all involve cell multiplication. ..

Space Lattice and Unit Cell - The constituent particles of a crystalline solid are arranged in a definite fashion in the three dimensional space. One such arrangement by representing the particles with points is shown below: fig 2.1 Such a regular arrangement of the co..

Prokaryotic and Eukaryotic Cells - There are two basic types of cells found in living organisms - the prokaryotic cells and the eukaryotic cells. This classification is based on three main features, namely; Organisation of biomembranes Nature of cyt..
