it was 1963 when they discovered that all organisms contained cells
It is simple.there are various fields..like marine,or birds mammals...etc... scientist in all this fields have discovered slowly slowly all this organism..and named them according to criteria
The kingdom Monera was proposed in 1866 by German scientist Ernst Haeckel, who classified all single-celled organisms without a distinct nucleus into this group. It has since been replaced by the domain Bacteria and Archaea in modern classification systems.

There are over hundreds of thousands of animals left in the entire world, and there are also organisms that are not even discovered, because every day scientist find a new organism and even new species of animals in the tropical rain forest and if you add all of them together, then there are over millions of species so more organisms are found each day.

the biospere is the sum of all of the earths ecosystems
The fact that all organisms have the same basic metabolism was discovered through research and comparison of biochemical pathways in different organisms. Scientists have identified commonalities in fundamental biological processes, such as glycolysis, Krebs cycle, and ATP production, which are universally present in all living organisms. This knowledge has advanced our understanding of the unity of life and evolution.
Theodor Schwann, a German physiologist, was the scientist who discovered that all animal cells have cells. He made this discovery in the early 19th century as part of his research on cell theory, which he developed alongside Matthias Schleiden.
