Microscopy of the dandelion flower

Here I show you how to observe the pappus of the dandelion. This is the part that carries away the seed with the wind.

Under the microscope #3 – Water fountain (with Spirogyra algae)

Here are some nice images of the alga Spirogyra. These algae have a spiral-shaped chloroplast. The video also shows other algae in colonies.
