The correct answer is option 'C: A.V. Leeuwenhoek'
Below is a detailed explanation:
First Observations of a Live Cell by A.V. Leeuwenhoek:
--------------------------------------------
Antonie van Leeuwenhoek, a Dutch scientist, was the first to observe and describe a live cell. He achieved this milestone in the late 17th century using a primitive microscope that he designed and built himself. Leeuwenhoek's microscopes were simple but powerful enough to magnify objects up to 300 times, allowing him to make groundbreaking discoveries in the field of microscopy.
Description of Live Cells:
--------------------------------------------
Through his observations, Leeuwenhoek described various types of live cells, including bacteria, sperm cells, and red blood cells. His meticulous observations and detailed drawings of these cells laid the foundation for the field of microbiology and provided valuable insights into the structure and function of living organisms at the cellular level.
Significance of Leeuwenhoek's Discoveries:
--------------------------------------------
Leeuwenhoek's discoveries revolutionized the scientific understanding of the microscopic world and paved the way for future advancements in biology and medicine. His work inspired other scientists, such as Robert Hooke, Theodor Schwann, and Matthias Schleiden, to further investigate the nature of cells and their role in living organisms.
Conclusion:
--------------------------------------------
In conclusion, A.V. Leeuwenhoek was the first to see and describe a live cell, marking a significant milestone in the history of science. His pioneering work in microscopy laid the groundwork for modern cell biology and continues to inspire researchers to this day.
