What did Matthias Schleiden contribute to cell theory?
Matthias Schleiden contributed to cell theory by asserting that all plants are composed of cells.
What was Rudolf Virchow's contribution to cell theory?
Rudolf Virchow contributed to cell theory by stating that all cells come from existing cells.
How did the invention of the microscope influence cell theory?
The invention of the microscope allowed scientists to observe and study cells, leading to the formulation of cell theory.
What is the significance of cells in multicellular organisms?
In multicellular organisms, cells work together to perform specialized functions, allowing for complexity and division of labor.
What is an exception to the cell theory?
Viruses are an exception to the cell theory as they are not composed of cells and cannot reproduce independently without a host cell.
