DEFINITIONS
It is a challenge for scientists and philosophers to define life in unequivocal terms.This is difficult partly because life is a process, not a pure substance.Any definition must be sufficiently broad to encompass all life with which we are familiar, and must be sufficiently general to include life that may be fundamentally different from life on Earth.Some may even consider that life is not real at all, but a concept instead.
BIOLOGY
We all know that the life Since has no unequivocal definition of life,and so the current understanding is only descriptive.The life is considered as the characteristic of something that exhibits all or most of the following traits.
Homeostasis:The Homeostasis is the Regulation of the internal environment to maintain a constant state.Let us consider the example,that the electrolyte concentration or the sweating to reduce the temperature..
Organization:Organization is structurally composed which has one or more cells has the basic unit of life.
Metabolism: Transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolism). Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life.
Growth: Maintenance of a higher rate of anabolism than catabolism. A growing organism increases in size in all of its parts, rather than simply accumulating matter.
Adaptation: The ability to change over time in response to the environment. This ability is fundamental to the process of evolution and is determined by the organism's heredity, diet, and external factors.
Response to stimuli: A response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis.
Reproduction: The ability to produce new individual organisms, either asexually from a single parent organism, or sexually from two parent organisms.
These complex processes, called physiological functions, have underlying physical and chemical bases, as well as signaling and control mechanisms that are essential to maintaining life.
