video: Flower Anatomy Under the Microscope The “Under the Microscope” video series includes some very good videomicroscopy of several subject specimens we’ll be “observing” in lab. Pay attention to the displayed magnification of each image. It is a You. Tube channel, so you’ll need to wade through some ads. There is no narration, so feel free to mute the eclectic musical score. https: //youtu. be/quk. Fl. Rnwm. Dc
