Visuals are definitely useful as a learning aid. I've never seen a video of the cell that was so detailed and animated. The video was able to cover many of the complex processes that occur within a single cell, covering topics from how leukocytes move to membrane composition to nuclear pores. Through watching the video, I learned that mitochondria's shape is influenced by its interaction with microtubules. Further empasized was the many roles of proteins in the cell. The video accurately depicted that biological molecules are comparable to infinitesimal machines.
