Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have..

The plasma membrane of each B cell should be sensitised by contact with a specific antigen for the release of antibodies. The plasma cells do not migrate to the site of infection but act through the lymph. So they form the humoral immune system. The B lymphocytes are short live..

Introduction - All living organisms need food for their existence. They need food for their growth, repair of tissues, energy and also protection against diseases. The various components of food are proteins, carbohydrates, fats, vitamins, minerals, roughage and wate..

The earliest attempt towards classification of living organisms is seen in the works of many ancient philosophers in Greek and India. The information available from many ancient scriptures of our country indicates the attempts made by Indians towards classification of plants and animals. ..

Humoral Immune System - The plasma b - cells produce a lot of anti-bodies, which circulate in the lymph. Each person can make 10 7 to 10 8 different kinds of antibody molecules so that there is an antibody for any antigen. The plasma membrane of each B cell should be sensitised by contact..
