Exploring Cell Structure and Function

The video tutorial introduces biotechnology, focusing on the use of living organisms to enhance human health and the environment. It explains the fundamental concepts of cell biology, including the structure and function of prokaryotic and eukaryotic cells. The tutorial delves into the roles of various organelles within eukaryotic cells, likening them to parts of a city. It also highlights the differences between plant and animal cells, emphasizing the importance of photosynthesis in plant cells. The video concludes with applications of cell manipulation in biotechnology labs for medical purposes.
