Which is not a characteristic of life?
Answers
Answer:
Explanation:
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others.
Answer :
Life is a unique complex organisation of molecules, expressing through chemical reactions which studied to growth, development, responsiveness, adaptation and reproduction.
We find some characteristics of life or living organisms which are not considered as defining property of a living organism.
Growth and production are not considered as defining properties of living organisms.
Growth can be understood by twin characteristics of living creatures. One of them is increase in mass and the other is increase in the number of individuals or cells.
It is an intrinsic property and occurs when the rate of anabolism is higher than the rate of catabolism.
In plants, cell division throughout the life takes place at some specific locations whereas, in animals, growth takes up to certain age only. (But sometimes cell division in animals occurs for replacement of lost tissues)
In unicellular, organisms grow through cell division and growth and reproduction are mutually inclusive events. Whereas, growth and reproduction for multicellular organisms are mutually exclusive events.
Reproduction is the ability to produce a new organisms by either asexual way or sexual way.
In sexual reproduction, genetic information of two individuals of different types is mixed in the offspring, whereas, in asexual reproduction, a single parent produces an offspring identical to the parent.
There are many organisms which are not able to reproduce offsprings.
Hence, growth and reproduction are non defining properties of a living organisms.
