Verified Answer
Directions: In the following questions, a statement of assertion (A) ...
Life originates from pre-existing life forms and the process is termed as biogenesis. According to Oparin and Haldane’s theory of biochemical origin of life, life originated spontaneously from non-living matter in the primitive atmosphere of earth (abiogenesis). Assertion is correct.
The primitive reducing atmosphere of Earth was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen and hydrogen. UV light, high temperature and lightning served as sources of energy for chemical reactions between above-mentioned gases to form simple organic compounds which in turn produced more complex organic compounds and finally the first living cell. The reducing atmosphere and absence of life on primitive Earth favoured the origin of life which is not possible in present day oxidizing atmosphere because the compounds are readily oxidized as soon as they are formed. Thus, now life is not originating spontaneously but only biogenesis exists. Reason is correct.
