Dutch scientist Anton van Leeuwenhoek.
The first scientist to observe living organisms with a microscope was Antonie van Leeuwenhoek in the 17th century. He is known as the "Father of Microbiology" for his groundbreaking discoveries using primitive microscopes of his own design.
Because they were discovered and exist in living organisms.
The scientist Franceso Redi was the first scientist to infer how organisms have arisen.
Anton Van Leeuwenhoek was first scientist who studied pond water and observed , discovered and described many organisms in 1773 .
The first scientist to observe microscopic organisms, which he referred to as "animalcules," was Antonie van Leeuwenhoek. Using his homemade microscopes in the late 17th century, he discovered these tiny living entities in various substances, including pond water and dental plaque. His pioneering work laid the foundation for microbiology and significantly advanced the understanding of microscopic life.
Scientists data can only date back to when these simple, unicelluar organisms lived and thus believe other living organisms evolved through them.
It was discovered first in 1885 by an American scientist named salmon.
Radioactivity was first discovered in 1896 by the French scientist Henri Becquerel.
The scientist who first studied living cell was A.V. Leeuwenhoek in 1674
Over 2000 years ago, a Greek scientist named Aristrotle(AIR uh staht ul) was one of the first people to classify living things.
animal classifiers classify animals... its their job
Antonie van Leeuwenhoek discovered living cells in pond water in the 17th century. Using a homemade microscope, he observed "animalcules" swimming in a droplet of pond water, which were later identified as single-celled organisms. This marked the first observation of living cells under a microscope.
