How did anton van leeuwenhoek contribute to the cell theory

Anton Van Leeuwenhoek contributed to cell theory through his observations where he first described living cells as red blood cells.

Cell theory is the part of current biology that explains the constitution of living things based on cells.

Anton Van Leeuwenhoek (1675), discovered that blood was also made up of cells and also discovered the existence of microorganisms made up of a single cell, which today we know as bacteria and protozoa.

In this way, through his observations it was possible to establish some of the fundamental principles for biology, reaching the conclusion of one of the main contributions of Anton va Leeuwenhoek to cell theory was: first, that all living organisms are formed by cells.

Hello!

Anton van Leeuwenhoek's most important discovery was single-celled things which were alive. He developed a method for creating powerful microscope lenses.

Using these, he discovered bacteria, vacuoles, protists, and some other things (which can be considered less important). His observations disproved spontaneous generation, which is the idea that living things are generated spontaneously. These observations helped lay the basic foundations for cell theory.
