unit on 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 (..

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 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 particles of a crystal in a three dimensional spac..

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..

All living organisms are composed of structural and functional units called cells. The body of a living organism may be composed of a single cell - as in unicellular organisms or many cells - as in multicellular organisms. The number of cells ..

Summary - All living organisms are composed of one or more cells. A cell is the structural and functional unit of life. The metabolic reactions in a living organism - can occur only in a delicately balanced environment. Through their unique chemical composition, c..

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 ..
