Cell Structure and Function Concepts

The video tutorial introduces the concept of cells, the smallest unit capable of life processes, and their discovery by Robert Hooke in 1665. It explains cell theory, which states that all living organisms are made of cells, and describes the functions of organelles within cells. The tutorial also covers the plasma membrane, ribosomes, RNA, and DNA, highlighting their roles in cellular functions and genetic material. The content is designed to provide a foundational understanding of cell biology.
