Question

Theory of spontaneous creation was supported by

• A. Van Helmont
• B. Redi
• C. Spallanzani
• D. Pasteur

Answer 1

The correct option is A Van Helmont

Van Helelmont
Theory of spontaneous generation states that life originated spontaneously from non living things.
This theory was supported by Van Helmont who believed that young mice could arise from wheat grains when the grains were put in a dark room along with a moist dirty cloth.

Redi
In his experiment, Francisco redi demonstrated that maggots could not be created from meat but its smell attracted flies which laid eggs on it that developed into maggots. The aim of his experiment was to disprove the theory of spontaneous generation.

Spallanzani
Spallanzi boiled hay infusion in 8 bottles and made four of them airtight while the other four were simply corked. After a few days, he observed that no microorganisms appeared in the air tight bottles whereas the hay infusion in the corked bottles showed a thick growth of microbes. This confirmed that microorganisms did not arise spontaneously from the broth and disproved the theory of spontaneous generation of life.

Pasteur
Louis Pateur performed an experiment to disprove the theory of spontaneous creation.

Final answer
(A) Van Helmont
