CELLS was first used in 1665 that refers to tiny units of life. British scientist named Robert Hooke was one of the earliest scientist to study under a microscope. Hooke made an important discovery that paved the way for the Cell Theory.
Oh! This slice of cork looked like a honey comb. Made up of tiny units and has chambers.
Schwann, I observed that plant tissues are also composed of cells. I should talk to Schwann so that he can also have an idea about this
A German botanist named Matthias Schleiden discovered observations between plant tissues that composed of cells. Schleiden later had gone to Schwann, his fellow scientist to discuss about his observation.
Oh Schwann come and take a look on what i observed.
Later on, a German physiologist named Theodor Schwann, made an observation after a conservation with Schledein. Plant and animal tissues have similarities. This idea became the foundation of plants and animals are cells.
Let me see? Does plant cell and animal cells have similarities?
After working for months, finally I have some convincing evidences that cells are derived from other cells.
In 1852, a prominent neurologist and embryologist named Robert Remak published an convincing evidences about cells.
I should publish an essay about cell entitled "Cellular Pathology"
Three years later, a well respected pathologist named Rudolf Virchow published an editorial essay entitled "Cellular Pathology" which was similar to Remak's work. This created a controversy as to which scientist should give credit for articulating cell theory.
