classification of living organism animation

Summary - Biologists estimate that there are about 30 million species of living organisms inhabiting this biosphere and only a million and half of it have been discovered and described so far. The species of plants and animals identified so far exhibit a great deal of ..

Introduction - Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the world. The diversity we see today is the result of 3.5 billion years of organic evolution. During the course ..

Need for Classification - More than a million species of living organisms have been discovered and described so far and a large number of them are yet to be discovered. Scientists involved in this task, called taxonomists, estimate that there may be around 30 million s..

Introduction - The present system of classification, recognises the living organisms under five kingdoms namely 1. KINGDOM: MONERA 2. KINGDOM: PROTISTA 3. KINGDOM: MYCOTA (FUNGI) 4. KINGDOM: METAPHYTA (PLANTS) 5. KINGDOM: METAZOA (ANIMALS) Let us now go into ..

Metals in the Living System - Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which carries oxygen to var..

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..

The micro-organisms like cyanobacteria (blue-green algae) and photosynthetic bacteria can also fix nitrogen. Some cyanobacteria also act as symbionts and are present in association with lichens; liverwort - Anthoceros; fronds of water fern - Azolla and roots of a gymnosperm - Cyc..

Summary - The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans cells show the presence of a cell coat outside the c..
