What was Virchow's contribution to the cell theory?
" all cells arise from cells". This means cells reproduce by cells. He also hypothesized that cells divide to form new cells. He also proposed that every cell came from a cell that already existed. His observations and conclusions and those of others are summarized in the cell theory. ...

Describe two observations of early scientists that support the cell theory?
One observation of early scientists that supports the cell theory is that all cells divide which was observed in 1855. The other observation was that living things contain cells which was observed in 1839 by Theodor Schwann. ...

Who are the people behind the cell theory?
In the 1830's the German scientist Matthias Schleiden observed a variety of plants and concluded that all plants are composed of cells. Another German scientist, Theodor Schwann, made similar observations on animals. The observations and conclusions of these scientists are summarized as the cell theory, one of the fundamentals of modern biology. THEODOR SCHWANN, MATTHIAS SCHLEIDEN, ANTON VAN LEEUWENHOEK,ROBERT HOOKE and RUDOLF VIRCHOW are responsible for the cell theory. ...

Why could scientists not see cells before the microscope?
The cells are too small for scientists to see with the naked eye. For some perspective on how small cells are, the dot above the letter 'i' is about the size of fifty cells. Scientists could not see regular cells with the eye alone. ...

What events lead to the discovery of the cell theory?
Back then, Robert Hooke found cells from a cork and named it cells. Later on, Matthias Schleiden found cells from plant parts and concluded that all plants are made of cells. Theodor Schwann, after observing many different animal cells, concluded that all animal have cells. Several years later, Rudolf Virchow hypothesized that cells divide to form new cells. Virchow proposed that every living organism has cells. His observations and conclusions and those of others are summarized in the cell theory. ...
Who is the first scientists to observe living cells?
Antonie Van Leeuwenhoek is the first who observe the tiny, unicellular living things but Robert Hooke is the one who confirmed Leeuwenhoek's observations and was the first to use the term cell.. ...

Explain how scientists developed the cell theory?
Scientists have been studying living things for over 400 years. At first, they made observations with their unaided eyes. Later, the development of the microscope allowed scientists to see cells for the fi rst time. Aft er observing many diff erent living things under the microscope, scientists realized that all living things are made up of cells. Th is conclusion led scientists to develop the cell theory-an explanation that summarizes the basic characteristics of living things. Th e cell theory states the following: • All living things are...

What caused scientists to discover the existence of cells?
Scientists discovered cells once the microscope was perfected. With the microscope, people could look at cells and the other building blocks of life for the first time. ...
