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 cells..

The smallest three-dimensional portion of a complete space lattice, which when repeated over and again in different directions produces the complete space lattice. The size and shape of a unit cell is determined by the lengths of the edges of the unit cell (..

The cell is the fundamental structural and functional unit of living organisms. Cells need energy for active transport, to move molecules between the environment and the cells across cells or within cells. Cells obtain ener..

Cell as a Self Contained Unit - The cell whether in a unicellular organism or a multicellular organism is capable of exhibiting some of its functions independently. Thus, the cell shows functional autono..

All living organisms, whether plants or animals, are made up of microscopic units called cells. The cell occupies the same central position in biology as the atom in the physical science..

The simplest structural units into which a complex multicellular organism can be divided and still retain the functional characteristic of life, are called cells. One of the unifying generalisations of biology is that certain fundamental activities are common to almost all ..

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 constituent ..
