Cell Biology Concepts and Functions

The video introduces cell theory, explaining that cells are the basic units of life. It covers the types of microscopes used to view cells, including light and electron microscopes. The structure and function of plant and animal cells are detailed, highlighting components like the nucleus, mitochondria, and cell membrane. The video also distinguishes between unicellular and multicellular organisms and discusses cell specialization, providing examples such as root hair cells and nerve cells.
