Detailed explanation-1: -The combined observations of Mattias Schleiden, Theodor Schwann and Rudolph Virchow resulted in the formation of the cell theory. Which of the following is not part of the cell theory? All cells contain a nucleus. All living organisms are made of one or more cells.
Detailed explanation-2: -The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells.
Detailed explanation-3: -Zeiss established a factory in Jena and continued to work on microscopes and microscope lenses. With the help of these more powerful and advanced lenses, Schleiden and Schwann developed their cell theory through microscope observation and experiments.
Detailed explanation-4: -Virchow’s greatest accomplishment was his observation that a whole organism does not get sick-only certain cells or groups of cells. In 1855, at the age of 34, he published his now famous aphorism “omnis cellula e cellula” (“every cell stems from another cell”).
