Differences Between Prokaryotic And Eukaryotic Cells Essay
The difference in sizes between the two types of cell relates to their cellular function as the cellular metabolism sets a limit on cell size. Some bacteria called mycoplasmas are the smallest cells known and have enough enzymes to carry out activities necessary to sustain themselves and reproduce. As eukaryotic cells are larger in size, they have a larger amount of DNA and enzymes in order to sustain themselves and carry out more cellular functions. The plasma membrane functions as a barrier that allows oxygen, nutrients and waste in and out of the cell. This means surface area to volume ratio is very important (Reece et al. 2010). Prokaryotes are smaller than eukaryotes and therefore have a larger surface area to volume ratio, therefore more substances can pass through the plasma membrane per second.
The most obvious difference between eukaryotic and prokaryotic cells is that eukaryotic cells…
