The German biologist, Walter Flemming, was the first to microscopically observe what processes?
1 Answer
Walter Flemming was a German anatomist and founder of the science of cytogenetics.
Explanation:
He developed a new staining technique in 1879 using synthesised aniline dyes to identify chromosomes and the structure of the cell nucleus. He found that these dyes revealed a thread like material in the nucleus.
He applied these stains to cells killed at various stages of division. Thus preparing a series of slides that upon microscopic observation clearly established the sequence of changes occurring in the nucleus during cell division. This allowed the systematic observation of mitosis, a term first used by Flemming for cell division, in far greater detail than before.
In 1882, Walther Flemming published the definitive study of cellular process of mitosis in the book "Cell substance, Nucleus and Cell division."
