Eukarya

Mr. Anderson introduces the domain Eukarya, highlighting its characteristics and diversity. He explains the features of eukaryotic cells, such as having a nucleus and organelles, and contrasts them with bacteria. The evolution of eukaryotic cells is discussed, focusing on the endosymbiotic theory and infolding. The video also covers the diverse metabolism and reproduction methods of eukaryotic cells, including mitosis and meiosis.
