Two ways bacteria and the fungus Penicillium are similar in that they are both cells with cell walls and membranes.
However, these two cells are very much different with respect to each other in many ways. Bacteria, in terms of the cell wall, has a soft cell wall in which the main component is peptidoglycan while for fungi their cell wall is mostly made up of chitin which makes it hard.The other similarity is that they are both heterotrophs (obtain their food the same way) that is they obtain food from complex organic compounds. They use cellular respiration for obtaining energy.Bacteria are not only responsible for the disease, but some of them are also very useful to us.
