Robert Hooke is credited with being the scientist who first observed cells under a microscope. He observed and described cells in a thin slice of cork in his book "Micrographia" published in 1665.

The specimen or sample being examined under a microscope is typically referred to as the "specimen." This can be anything from cells, tissues, or other material being studied or observed under the microscope.

The first person to witness a live cell under a microscope was Antonie van Leeuwenhoek in the 17th century. Using a simple microscope he designed, he observed single-celled organisms in various forms of life.
Anton van Leeuwenhoek is the Dutch scientist who first observed sing celled organisms under a microscope. Leeuwenhoek is considered the first microbiologist.

Robert Hooke discovered cells under a microscope in 1665. He took a sliver of cork and called the small encasements he saw, cells. They were dead cells, though. The first person to see living cells, was a man named Anton van Leeuwenhoek. He took pond water and observed that under a microscope.
The shortest object in a microscope is called the "specimen" or the "sample." It is the object or material being observed under the microscope.
The first thing looked at under a microscope was likely a biological specimen, such as a plant cell or animal tissue, in the 17th century. The microscope allowed scientists to observe these tiny structures in detail for the first time.
