Question

Что такое биогенез. срочно нужно помогите пожалуйста

Answer 1

(от био … и …генез), образование органических соединений живыми организмами. В широком смысле биогенез - эмпирическое обобщение, утверждающее, что все живое происходит только от живого. В сер. 19 в. биогенез противопоставляли ненаучным представлениям о самозарождении организмов (червей, мух и др.). Как гипотеза о вечности жизни биогенез несостоятелен. Ср. Абиогенез.

Answer 2

What is Biogenesis?

Biogenesis refers to the process by which living organisms are produced from other living organisms. It is the principle that living things can only arise from other living things, and not from non-living matter. This concept is in contrast to the idea of spontaneous generation, which was a popular belief in ancient times that living organisms could arise spontaneously from non-living matter.

Biogenesis is a fundamental concept in biology and is supported by extensive scientific evidence. It is a cornerstone of the theory of evolution, as it explains how new species arise through the process of reproduction and inheritance. The study of biogenesis encompasses various fields, including genetics, cell biology, and evolutionary biology.

Historical Background

The concept of biogenesis emerged as a result of scientific experiments and observations conducted in the 17th and 18th centuries. One of the key figures in the history of biogenesis is Louis Pasteur, a French chemist and microbiologist. In the mid-19th century, Pasteur conducted experiments that disproved the theory of spontaneous generation and provided evidence for the principle of biogenesis.

Pasteur's experiments involved sterilizing nutrient-rich broth and then exposing it to the air. He found that no microorganisms grew in the broth unless it was exposed to air containing microorganisms. This experiment demonstrated that living organisms do not arise spontaneously from non-living matter, but rather come from pre-existing living organisms.

Significance of Biogenesis

The principle of biogenesis has significant implications for our understanding of the origin and diversity of life on Earth. It supports the idea that all living organisms share a common ancestry and have evolved through a process of descent with modification. It also provides a basis for studying the mechanisms of reproduction, inheritance, and evolution.

Biogenesis is a fundamental concept in fields such as microbiology, genetics, and evolutionary biology. It helps scientists understand how new species arise, how genetic information is passed from one generation to the next, and how organisms adapt to their environment over time.

Conclusion

In summary, biogenesis is the principle that living organisms can only arise from other living organisms. It is supported by scientific evidence and has important implications for our understanding of the origin and diversity of life. The concept of biogenesis emerged as a result of scientific experiments conducted in the 17th and 18th centuries, and it continues to be a fundamental concept in biology today.
