Prokaryotes and eukaryotes.

If humans were prokaryotes we would be unable to perform various activities essential to everyday life. For example, our ability to engage in aerobic respiration would be greatly reduced since prokaryotic cells lack mitochondria needed to produce energy from oxygen. Additionally, since prokaryotes do not have specialized compartments like those found in eukaryote lysosomes they could not carry out processes such as digestion or waste removal from within cell itself (Bailey et al., 2016). Without these abilities humans would face extreme difficulty functioning without assistance from external sources like food or oxygen tanks. In conclusion it is evident that there are numerous differences between the two types of species even though both share similarities at an overall level. Humans represent just one example of countless eukaryotes species who benefit from having sophisticated internal structures which allow them to carry out advanced survival functions with ease. It can thus be appreciated how much different life on earth would be if all organisms were composed solely of primitive prokaryotic cells; lacking many essential features required for basic living conditions such as digestion and respiration.
