advantage of cell specialization

Simple epithelium may sometimes become modified for some specific functions. Two such modifications are very common, namely, ciliated epithelium and glandular epithelium. Ciliated epithelium is always a modification of columnar epithelium. Here, the cells are characterized by the presence..

Spontaneous redox reactions are the metal displacement reactions. Therefore such reactions have been used for producing electricity. This is done by carrying out these reactions in specially designed units called electrochemical cells. An electrochemical cell is a dev..

In some plants, the roots undergo modification to perform special functions, such as storage and respiratio..

Rectangles, rhombuses and squares belong to the set of parallelograms. Each of these may be defined as a parallelogram as follows: A rectangle is an equiangular parallelogram. A rhombus is an equilateral parallelogram. A square is an equilateral and equiangular parallelogram. Thus a square is both ..

1) When both the cars are moving in the same direction, i.e., q = 0 0 degrees. Thus, the relative speed between two bodies moving in the same direction is equal to the difference of the individual speeds of two bodies. 2) When the two cars are moving along parallel lines in opposite direction, i.e...

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 energy by oxid..

1) More efficient than conventional cells because the energy of the fuel is converted directly into electric energy. Efficiency = 60-70%. 2) They are free from polluti..
