About 2.5 billion years ago, oxygen began slowly to accumulate in the atmosphere, as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage, and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic bacteria. Other cells may have become symbionts with larger cells and evolved into mitochondria. As the amount of

with a coencytic organism forming cellulorization with individual cells developing membranes, then tissues became more specialized forming a multicellular organism. There are some advantages of multicellularity such as having specialization of cells which creates a division of labor, leading to greater efficiency. Another advantage is multicellular organisms have a larger size which provides protection from predators. Fungi are large and have a large surface area to volume ratio, allowing them to absorb nutrients more efficiently.
