Exploring Cell Structure and Function

This podcast reviews unit two, part one, focusing on cell structures, their functions, and classification. It covers eukaryotic cell components, cell membranes, and transport mechanisms. The differences between prokaryotic and eukaryotic cells are highlighted, along with the classification of living organisms into domains and kingdoms. The podcast concludes with a discussion on viruses, their characteristics, and how they differ from living cells.
