They were known for inventing the compound optical microscope. It made it easier and more efficient to observe cells. It helped many people learn more about cells
He was one of the first to use a microscope for the research of cells. He studied the organs of animals. He found the function of many organelles.
Hooke designed a microscope. He observed a piece of cork and looked at its structure. He came up with the "cell". He worked on engineering the microscope.
Anton Van Leeuwenhoek
He made improved lenses for microscopes. He studied animals with a single cell. He learned about bacteria.
Redi wanted to prove an idea wrong. Many people believed that maggots came from meat. Francesco set up experiments to show that cells can only be made from other cells. This was an important idea in the cell theory.
He recognized the importance of the nucleus. He was a German botanist and was the co-founder of the cell theory. He also studied cell division.
Theodore and Matthais came up with a conclusion. They were both botanists and studied plants. Plants are made up of one cell. The cell is the building block of all plants.
