1. The Microscope: The invention of the microscope in the 17th century was crucial. It allowed scientists to see objects too small for the naked eye, including cells and their internal structures.
2. Improved Staining Techniques: Staining techniques were developed in the 19th century, allowing scientists to differentiate different parts of the cell and see the process of cell division in more detail. These techniques highlighted the chromosomes and other structures involved in mitosis and meiosis.
These two technologies combined provided the necessary tools for scientists to study cell division in detail and ultimately understand the mechanisms behind this fundamental process.
