Cell Structure and Function Concepts

The video tutorial covers the basics of cells, including their discovery and the development of cell theory. It explains the differences between prokaryotes and eukaryotes, highlighting their characteristics and types. The tutorial also guides students on how to compare and contrast these two groups using a Venn diagram.
