In this episode of 'Dude with a Microscope', the host explores why drinking seawater is harmful. The video begins with an introduction to plant cells, highlighting their structure and the role of chloroplasts in photosynthesis. It then demonstrates the effect of salt water on plant cells, showing how they shrivel due to osmosis. The concept of osmosis and semi-permeable membranes is explained, emphasizing how salt attracts water. The video warns against drinking seawater, explaining that it would dehydrate human cells similarly. The episode concludes with a call for viewer suggestions.
