What was Robert Brown’s first hypothesis?
At first Brown thought the pollen grains were moving because they were alive. So he looked at some 100 year old pollen grains on water and observed the same type of random motion. These old grains were definitely not alive and he could not explain the movement of the tiny particles that was called Brownian motion.

Mitochondria, often referred to as the “powerhouses of the cell”, were first discovered in 1857 by physiologist Albert von Kolliker, and later coined “bioblasts” (life germs) by Richard Altman in 1886. The organelles were then renamed “mitochondria” by Carl Benda twelve years later.

The nuclei of most eukaryotic cells are generally round or oval shaped and smooth. Nevertheless, alterations in nuclear morphology are observed in various physiological processes and pathologies. A classical example of nuclear shape changes under physiological conditions are the nuclei of neutrophil granulocytes.
