Robert Hooke was looking at slices of thin cork through a microscope at 50x.
Saw honey-combed like compartments in the slices.
He then termed the storage-rooms as "cells".
He described "cells" as the basic unit of life.Han and Zacharias Janssen created
the first compound optical microscope that
magnifies to 9x.
By doing this, it contributed to the cell theory,
making it easier and more practical
to observe cells.Some
event
happenedAnton van Leeuwenhoek
was the first to see and describe bacteria,
yeast plants, the action in a drop of water,
and the circulation of blood corpuscles
in capillaries.Matthias Schleiden stated
that different parts of a
plant organism is made
of cells. Along with Schwann
became the first to formulate an
informal belief of the atomic theory
of chemistry. Recognized the importance
of the cell nucleus and observed its connection
with cell division.Theodor Schwann found
similar structures related to Schleiden's
discovery that all plants are made of cells.
Schwann concluded "All living things
are composed of cells and cell products".
Thus, became the cell theory.Rudolph Virchow proposed that
all cells come from pre-existing cells.
He thought of "every cell from a pre-existing cell
became the foundations of division".
He also stated that not all plants are made
up of cells, which then led to the creation of the cell theory.
