The video tutorial by Sarah covers the basics of organelles found in prokaryotic and eukaryotic cells. It explains the differences between prokaryotic cells, like bacteria, which lack a nucleus, and eukaryotic cells, such as animal and plant cells, which have a nucleus and more complex structures. The tutorial also discusses the unique features of protists, including their movement and response to light. Key organelles like the nucleus, mitochondria, chloroplasts, and ribosomes are highlighted, along with their functions in cellular processes.
