Cell Biology Concepts and Processes

The video introduces life functions and the cell as the basic unit of life. It reviews biomolecules and their role in forming cells, compares unicellular and multicellular organisms, and explains cell specialization. The differences between eukaryotic and prokaryotic cells are discussed, along with an overview of cell structures and their functions. The video also highlights the differences between plant and animal cells, concluding with a recap of key points.
