Can any one tell what is the criteria for a cell(biological) to be living ?

Answer 1

There are 7 characteristics of life: homeostasis, organization, metabolism, growth, adaptation, response to stimuli, and reproduction.

Homeostasis - maintaining the stable internal environment via the cell membrane as a previous poster mentioned

Organization - some form of recognizable organization

Metabolism - acquiring energy

Growth - self explanatory

adaptation (evolution) - also self explanatory

response to stimuli - also self explanatory

Reproduction - using a nucleic acid based information system


Movement is not a characteristic of life. Have you seen the grass walking around lately?

Answer 2

Defining a living thing is a difficult proposition, as is defining “life”—that property possessed by living things. However, a living thing possesses certain properties that help define what life is. Here are a few generalizations....

Living things have a level of complexity and organization not found in lifeless objects. For instance, cells, tissues, organs, organ systems, then an organism. Also, living things exhibit a rapid turnover of chemical materials, which is referred to as metabolism. All living things are able to respond to stimuli in the external environment, which is known as responsiveness. Growth requires an organism to take in material from the environment and organize the material into its own structures. A living thing has the ability to produce copies of itself by the process known as reproduction. Finally, populations of living organisms have the ability to adapt to their environment through the process of evolution.
