Question

Bacteria are only able to be produced from other bacteria already existing on earth.

Which theory best describes this?

Answer 1

Biogenesis is the theory that explains that bacteria can only be produced from existing bacteria, a concept that is also part of the cell theory, affirming that all cells originate from pre-existing cells.

Step-by-step explanation:

The theory that best describes the assertion that “life only comes from life” was stated by Louis Pasteur, and it is known as biogenesis. This theory is also a fundamental part of the cell theory, which states that all cells come from pre-existing cells. This principle was further developed by Rudolf Virchow, who hypothesized that this applies to all cells, including bacteria. It refutes the earlier theory of spontaneous generation, which claimed that living organisms could arise from non-living matter. The cell theory has been crucial to our understanding of biology and underlines the reproduction of bacteria, which reproduce by dividing and forming new bacteria from existing ones.

Answer 2

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). Bacteria do not grow and multiply the same way as animals or humans. They take in nutrients and reproduce by dividing – one bacteria splits and becomes two bacteria, two become four, four become eight and so on.
