Eukaryotic and Prokaryotic Cells

Professor Lucas from Biologia Ilustrada explains the differences between prokaryotic and eukaryotic cells. Prokaryotic cells, such as bacteria, lack a nucleus and have simpler structures, allowing rapid multiplication. Eukaryotic cells, found in plants, animals, and fungi, have a true nucleus and complex organelles. The video compares these cell types, highlighting their similarities and differences, and concludes with a call to action for viewers to engage on social media.
