Question

Which statement is true about the cell theory? It is based on observation. It is based on a random guess. It is unchangeable and permanent. It is a claim posed by some scientists.

Answer 1

Answer: It is based on observation.

Cell theory as the name suggest tells that every living organism is composed of tiny cells. First cells were observed on a microscope by Hook. He saw small dots using a microscope and called these tiny dots as cell. Later as the microscopes developed the picture of cell became clear. So, it was the Hook's observation that led to cell theory.

Answer 2

The cell theory was based on an observation. The cell was first discovered by Robert Hooke in the late 1600s. His discoveries were narrated in detail in his book Microphagia. In the said book, he gave 60  detailed observations of various objects under an uncouth, compound microscope. One of the observations was from a very thin slice of bottle wine cork. Hooke had discovered tiny pores that he later on named as "cell" which came from the Latin word "cella" meaning a small room where monks live. Hooke was neither aware of the real structure of cells nor its functions because, during that time, microscopes had low magnification which prevented him from unraveling other internal cellular components.
