green living systems

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..

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 oxy..

Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common goals. In the living sys..

Blue green algae are autotrophic and nitrogen fixing organisms unlike heterotrophic and symbiotic nitrogen fixing microbes discussed above. They manufacture their food by photosynthesis, as they have chloroplasts. Hence, they can live independently. BGA like Anabaena and N..

Root is the descending portion of the axis of the plant. It is not normally green in colour. It is characterised by the absence of nodes and internodes. There are two types of root systems, the tap root system (seen in dicots) and fibrous root system (seen in..
