what does cell specialization mean

The 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..

>As copper is lower in the metal activity series, it does not undergo a similar reaction and hence remains a region of deficiency of electrons. So, when the zinc plate and the copper plate are connected by means of a metal wire, free electrons from the zinc plate flow to the cop..

Being Alive - What does it mean? - Living organisms, like any non-living matter, are composed of some basic elements. The same physical laws such as gravitation, magnetism, thermodynamics etc., also bind living organisms. Yet, living organisms differ from non-living in..

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..

A population of identical molecules (genes), cells or organisms, all of which are derived from the same parent by asexual means, is known as a clone 1 . The process of producing genetically similar molecules, cells, or organisms from a common precursor by asexual..

.8 - Cell Structure of Cyanobacteria The planktonic forms contain gas vacuoles in their cells to help in floating. Some cyanophycean members possess special types of cells called heterocysts, as in Anabena and Nostoc. They are large, thick walled, round ..

An electrolytic cell consists of a container made either of glass, or any suitable plastic material called electrolytic tank, which is a bad conductor of electricity. Two electrodes (rods or plates) are placed in the tank and it is filled with the solution of the electrolyte or with molt..
