What are the main components of the Cell Theory?

Three main parts: all organisms made of cells, cell is fundamental unit, cells originate from preexisting cells.

How did Anton van Leeuwenhoek contribute to the Cell Theory?

Discovered bacteria by examining dental scrapings with a microscope.

Matthias Schleiden and Theodor Schwann

Rudolph Virchow's research on cells coming from preexisting cells.

Zacharias Janssen's invention of the compound microscope in the early 1600s sparked interest in the Cell Theory, laying the foundation for the understanding that all organisms are made of cells, which are the fundamental units of structure, and that cells come from preexisting cells.
Matthias Schleiden and Theodor Schwann's work in the 1800s solidified the Cell Theory by independently concluding that all plants and animals are composed of cells, with Rudolph Virchow's research further supporting the idea that cells originate from preexisting cells.

The Cell Theory consists of three main parts: all organisms are made of one or more cells, the cell is the fundamental unit of structure in organisms, and all cells originate from preexisting cells.
The history of the Cell Theory traces back to the early 1600s in the Netherlands, where Zacharias Janssen is credited with inventing the compound microscope, sparking a wave of interest among naturalists and scientists.
Anton van Leeuwenhoek, a Dutchman, constructed his own microscope and discovered bacteria by examining dental scrapings, referring to them as "animalcules."
The Cell Theory was further developed in the 1800s by Matthias Schleiden and Theodor Schwann, who independently concluded that all plants and animals are composed of cells, leading to the final part of the theory that cells come from preexisting cells, solidified by Rudolph Virchow's research.
