what actually is the cell theory and the three parts
What actually is the cell theoryand the three parts.
  • The cell theory is simple. It says that “all living organisms are composed they may be unicellular or multicellular.”
  • “The Cell is the basic unit of life.”
  • “Cells arise from pre-existing cells. “
  • What are unicellular and multicellular organisms? A unicellular organism is any life form that consists of just a single cell. Most of life is unicellular, with bacteria serving as the majority. The main groups of unicellular life are bacteria, Achaea (both prokaryotes), and the eukaryota (eukaryotes).

Do I think the knowledge of cells would have developed without microscopes?
  • No. Why? Well let me start with this. We have a magnifying glass, which can only zoom in a few centimetres. This is not nearly enough to look at small cells, such as blood cells, all we would see would be a smear of pinkish red. It’s probably almost impossible to look at cells without microscopes. I even think ( for example) there wouldn’t be as many crims behind bars, if it wasn’t for samples taken and look at under microscopes, for evidence.
what is the theory of spontaneous generation and whose idea it was it and who disapproved of it
What is the theory of spontaneous generation and whose idea it was it and who disapproved of it.
  • Spontaneous generation or Equivocal generation is an theory regarding the origin of life. From inanimate matter, which held that this process was a commonplace and everyday occurrence, as distinguished from univocal generation, or reproduction from your parent(s). The theory was synthesized by Aristotle, who compiled and expanded the work of prior natural philosophers and the various ancient explanations of the appearance of organisms. It is generally accepted to have been ultimately disproven in the 19th Century by the experiments of Louis Pasteur, who is in the list of this assignment , expanding upon the experiments of other scientists before him (such as Francesco Redi who had performed similar experiments in the 17th century). Ultimately, it was succeeded by the cell theory.
