Question

Which among the following was proven by Louis Pasteur?

• A. Life comes only from the pre-existing life
• B. Theory of special creation
• C. Oparin-Haldane theory
• D. Spontaneous generation theory

Answer 1

The correct option is A Life comes only from the pre-existing life

The theory of spontaneous generation was strongly supported by Van Helmont. This theory states that life originated from the non-living matter spontaneously.

Louis Pasteur disproved the concept of spontaneous generation and provided evidence to support the concept which states that new life originated on earth from the pre-existing life forms. For example, a cell arises from a pre-existing cell, and flies develop from larvae.

Theory of special creation believes that life was created by a supernatural power, life has not changed or diversified since its origin and the earth is about 4000 years old.

Oparin and J.B.S.Haldane proposed that the first form of life could have come from pre-existing organic molecules. They believed that organic molecules were formed from inorganic materials.
So, the correct answer is 'Life comes from the pre-existing life'.
