When did zacharias janssen contribute to the cell theory?
Zacharias Janssen did not contribute to the cell theory. He is credited with inventing the first compound microscope in the late 16th century with his father, Hans Janssen. This invention was crucial for the development of cell theory by later scientists.
What did Zacharias Janssen do for the Cell Theory?
Zacharias Janssen did not directly contribute to the Cell Theory. The Cell Theory was primarily developed by scientists such as Matthias Schleiden, Theodor Schwann, and Rudolf Virchow in the 19th century. Janssen is known for inventing the compound microscope with his father, Hans, in the late 16th century.

What was Hans and Zacharias Janssen's contribution to cell theory?
Hans and Zacharias Janssen are credited with inventing the compound microscope, which played a crucial role in the development of the cell theory. Their microscope allowed scientists to observe and study cells for the first time, ultimately leading to the discovery of the cell as the basic unit of life.
What are Hans and Zacharias Janssen famous for and how did their invention help in the development of the present day cell theory?
Hans and Zacharias Janssen are famous for making the first "simple" microscope which helped to discover cells and that everything is made up of living cells etc. They help us understand the cell structures of a living thing.
Hans and Zacharias Janssen contribution to the cell theory?
Hans and Zacharias Janssen are credited with inventing the compound microscope in the late 16th century. Their invention allowed for the observation of cells for the first time, thus laying the groundwork for the development of the cell theory by later scientists such as Matthias Schleiden and Theodor Schwann in the 19th century.
What was Hans janseen contribution to the cell theory?
Hans contribution was in 1950 heinvented the first compound to be seen under a microscope by lining two lenses two produce Extra-Large images or viewing because you could not see organism's with the naked eye.
What was the contribution from Hans and zacharias janssen to the cell theory?
In 1950, dutch eyeglass makers, Hans and Zacharias Janssen ( exact dates unknown ), invented the first compound microscopes, by lining up two lenses to produce extra-large images and in doing so they created the compound microscope. They were inventors of the first compound microscope in 1595, which allowed for more in depth studies of cells.
