These pigments were later coupled to electron transport systems to also drive ATP synthesis. These prokaryotes release sulfur as a by product. Cyanobacteria are photosynthetic organisms belonging to the Moneran kingdom. The monerans evolved metabolic process known as photosynthesis from other metabolic processes. Explain the origin of chloroplast.
Eukaryotic cells are cells with a true nucleus.
A eukaryotic is thought to have originated when the plasma membrane of a cell pocketed inwardly pushing the chromosome into the center of the cell. This more central position protected the chromosome from being caught up into a food vacuole in which the DNA material of the cell might have digested . Eukaryotic cells ate aerobic bacteria and cyanobacteria in their environment. A mitochondrion is an organelle that carries out aerobic respiration in eukaryotic cells. The mitochondrion is thought to be an aerobic respiring bacteria that was eaten by a host eukaryotic cell and it was never digested and in time evolved into the mitochondrion organelle that could efficiently make more ATP than the process of glycolysis.
