Cell Biology Concepts and Functions

This video tutorial covers the structure and function of cells, the basic unit of all organisms. It explains how cells form tissues, tissues form organs, and organs form organ systems. The tutorial explores plant and animal cells, detailing their components such as the cytoplasm, cell membrane, and nucleus. It also discusses the functions of these components, including the role of the cell wall in plants and the observation of cells under a microscope.
