Inside the Cell Membrane

The speaker recounts their experience with a circular red spot on their arm during elementary school, which was later diagnosed as a fungal infection called ringworm. Despite expecting to be prescribed antibiotics, they were instead given an antifungal cream. This led the speaker to wonder why antibiotics weren't used to treat the infection, prompting them to research the differences between bacterial and fungal cells. They discovered that prokaryotic cells, including bacteria and archaea, have a simple cell structure with distinct differences in DNA, ribosomes, cytoplasm, and lack of nucleus compared to eukaryotic cells such as plants, animals, and fungi. Understanding these differences can help treat infections more effectively, the speaker concludes.
