Cell Structure and Function Review

This video tutorial covers a comprehensive review of biology topics for the ELC exam. It begins with an introduction to the exam's importance, followed by detailed explanations of cell structure and function, including the differences between prokaryotes and eukaryotes. The tutorial then explores transport mechanisms within cells, such as active and passive transport. It also delves into the categories and functions of organic molecules, including carbohydrates, lipids, proteins, and nucleic acids. The processes of photosynthesis and respiration are explained, along with a comparison of viruses and cells, highlighting the lytic and lysogenic cycles. Finally, the stages of the cell cycle and mitosis are discussed.
