Vital force theory was a concept in early medicine suggesting that living organisms possess a unique life force or energy that governs their growth, development, and functioning. This theory was prominent before the advent of modern scientific understanding and has largely been discounted in favor of biological explanations for life processes.

Who rejected vital force theory?
The rejection of the vital force theory was mainly attributed to the rise of modern scientific approaches in the 19th century, particularly with the advancements in chemistry and physiology. Scientists like Claude Bernard and Rudolf Virchow played key roles in challenging the vitalistic ideas by emphasizing the importance of understanding biological processes through physical and chemical principles rather than invoking a mystical life force.
What is vital force?
Vital Force Theoryis a theory made by the Swedish chemist BERZELLIUS in 1815, who put forward this theory that, organic compounds could be produced only under the influence of some mysterious force existing in living organisms. This mysterious force was called vital force. Since such mysterious force cannot be created artificially, it is impossible to synthesize organic compounds in the laboratory. This theory resigned supreme for a number of years. It gave serious set back to progress of organic chemistry. So, chemistry could not flourish for a long time.FAILURE OF VITAL FORCE THEORY:Vital force theory has been failed because a number of organic compounds can be prepared by inorganic or non-living stuff.FREDRICK WHOLER, a German chemist was the first person who, in 1828 synthesized an organic substance UREA by using inorganic substances. It was previously obtained from urine of animals. He obtained urea while evaporating an aqueous solution of Ammonium Cyanate (obtained by double decomposition of ammonium chloride and potassium cyanate) on boiling with water.(Both of the following reactions are carried out in the presence of heat)NH4Cl (s) + KCNO (s) ----------> NH4CNO (s) + KCl (s)NH4CNO (s) ------------> H2N-CO-NH2 (s)Urea (H2N-CO-NH2)This synthesis gave death blow to Vital Force Theory, thereafter thousands and thousands of organic compounds have been synthesized in the laboratory. With the down fall of Vital Force Theory, the term organic (pertaining to life) lost its original significance. However, it was shown that all organic compounds, whether natural or synthetic, essentially contain carbon and hydrogen and occasionally a few other elements such as oxygen, nitrogen, sulphur phosphorous and halogens.Organic compounds are now known as the compounds of carbon. Along with carbon, hydrogen and oxygen are also usually found, whereas nitrogen, the halogens, phosphorous and sulphur are sometimes present.The branch of chemistry which deals with the study of organic compounds is called organic chemistry.
Which of these is an element of the force theory of the origin of state?
The force theory posits that states emerge through the conquest and force by a single individual or a group. It suggests that the state's power and authority come from the ability to exert dominance over others.
How did Pasteur's experiment differ from spallanzanis experiment?
Pasteur's experiment refuted the theory of spontaneous generation by demonstrating that microorganisms in broth were killed by heat and could only enter through the air. Spallanzani's experiment involved boiling broth in sealed flasks to prevent microorganism entry, concluding that the lack of spontaneous generation was due to the lack of vital force rather than the absence of air.
What is synonym of indespensible?
Essential, vital, necessary.
How vital force is wrong?
It would be much shorter to list the ways in which the theory of "vital force" was right. Here they are, between the parentheses: ().
How rejected the vital force theory?
The vital force theory was rejected with the advancement of scientific knowledge in fields such as biology, chemistry, and physics. These disciplines provided more concrete explanations for biological processes that did not require the notion of a separate vital force guiding life functions. The discovery of cellular and molecular mechanisms further contributed to discrediting the vital force theory.
Why vital force theory is finally discarded?
The vital force theory was a theory presented by Berzelius. The 1809 theory stated that organic compounds could not be synthesized in a laboratory. The German Scientist contradicted the theory, and prepared Urea through Ammonium Chloride and Potassium Cyanate so eventually is was discarded.
What is a bathmism?
A bathmism is an obsolete term for a "growth force" in the theory of vitalism - the doctrine that life involves some immaterial "vital force".
Who disproved the vital theory?

Whose theory of evolution believes that every organism has an internal vital force?
The theory of evolution that believes every organism has an internal vital force is known as Lamarckism, proposed by Jean-Baptiste Lamarck. Lamarck believed that organisms could pass on traits acquired during their lifetime to their offspring, driven by a force he called "vitalism." However, this concept has been largely discredited in modern evolutionary biology.
