Cell Organelles and Their Functions

Mr. U provides a review of cell organelles, explaining the functions of the cell membrane, nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi complex, lysosomes, cytoskeleton, cell wall, vacuole, and chloroplast. Each organelle is compared to familiar objects to illustrate their roles in the cell, such as the nucleus being the cell's brain and mitochondria as the power plant. The video aims to help students understand the basic functions and importance of each organelle in maintaining cell life.
