How Diatoms Build Their Beautiful Shells

The video introduces the team behind 'Journey to the Microcosmos' and focuses on diatoms, microscopic organisms with significant ecological roles. It explains the structure and formation of diatoms' silica shells, known as frustules, and their contribution to photosynthesis and oxygen production. The video also discusses the ecological impact of diatoms, their lifecycle, and how they recycle silica in aquatic environments.
