LIVING????????????........

In the living world of biology, living can be conventionally and distinctively defined as the characteristics that a living organism exhibits and persists.

All living organisms Grow, Reproduce, Metabolism, Have Ability to Sense Environment and reflex a suitable response to a stimuli are some of the unique features that all living organisms posses.

All living organisms grow  from what is called as the building blocks of life" THE CELL". These cell grow and reproduce to create a particular living organism by undergoing several complex process of "Replication, Transformation, Translation" and various other minute complex processes. 

The cell divide themselves by the process of cell division, and this process continues throughout the life of a living individual especially in the case of plants. but in case of animals the growth occurs till a certain stage of life. 

Reproduction is another special process of living organism where a new progeny is formed from a older one, and the new one is either identical to the parents " As in case Plants", but in case of the animals the progeny are more or less similar to their parents which allows them to distinguish between them. In case of lower organisms true regeneration of the progeny is observed, where the parent either itself divides into two separate organism giving rise to the daughter cell or reproduce by the process of fragmentation.

Another important characteristics is "Metabolism". In this process all the chemical compounds which are solely involved in the process of living comes in action and plays some of the major roles by providing energy, stimulus, etc.

Another most important process is "Evolution". Life on earth began much earlier and from that point of time various organisms originated in this world. Among these organisms some of them got extinct due to several environmental catastrophies, and some other organisms which were resistant enough survived and managed to live and produce their progenies and continued their species. This process is defined as"Evolution". 

Therefore, we can say that living organisms are self-replicating, evolving and self regulating interactive systems capable of responding to external stimuli.
