They are, therefore, important to photosynthetic organisms for the purpose of producing food on their own and not needing to feed on other organisms to survive.
Because oxygen is one of the byproducts of photosynthesis, the chloroplasts are therefore a crucial site for producing such gas, which later is released from the cell into the environment. Oxygen is biologically important for its role, in turn, in various biochemical and physiological processes in animals. For further description and facts on photosynthesis, read Plant Metabolism tutorial. The Endosymbiotic theory was conceptualized to delineate the origin of chloroplasts.
The eukaryotic cell, being the larger cell, took in the smaller photosynthetic prokaryotes e. Eventually, the prokaryotes evolved and differentiated into plastids, particularly, chloroplasts. These early photosynthetic eukaryotes harboring prokaryotes-turned-organelles are presumed to be the early ancestors of modern plants and algae on Earth. The discovery of the cpDNA in chloroplasts, the similarity in membranes, and the binary fission as a means of reproduction serve as evidence that supports this theory.
