The process involves gaining entry into a cell without piercing the cell membrane. The plasma of the cell membrane engulfs the foreign material locking it inside and as a result, an intercellular vesicle form. The chloroplasts and the mitochondria resemble those of the prokaryotic ribosomes. The existence of the amoeba and other eukaryotic organisms that lack mitochondria are evidence for the necessity of the symbiotic relationship with the aerobic bacterium.
Single celled organisms are among the eldest organisms on earth. From fossil records, bacteria once covered the land we live on today. As a way of feeding, the bacteria started making their food from suns’ energy and carbon dioxide. The process had oxygen as a by-product that changed the earth’s atmosphere making the existence of other living organisms possible.
