He looked at blood, rainwater, scrapings from teeth through his own made simple microscope, and observed living cells; called some 'animalcules. He also discovered small 'animalcules' are now called bacteria.
-
He investigated and described osmosis, respiration, embryology, and the effect of light on plants. He has been given credit for discovering cell biology and cells in plants and the actual discovery of the process of osmosis.
-
observed that many cells had a dark structure near the center of the cell, which we now call the nucleus
-
He viewed plant parts under a microscope, and discovered that plant parts are made of cells.
-
He viewed animal parts under a microscope and he discovered that animal parts are made of cells.
-
He stated that all living cells come only from other living cells.
-
She is one of the co-founders of the cell theory. She demonstrated that the cell membrane is a physical structure.
-
She is best known for her research paper about endosymbiotic theory formulation which is the first to rely on direct microbiological observations .
