Preserved Volvox at 100x
A preserved slide of Volvox, showing just how sad they look on many preserved slides. Compare this to my image of the live Volvox to see the difference. Volvox are a colonial green algae, where each colony forms a large sphere made from hundreds of individual cells. This slide does nicely show how the colonies are made from large sheets of cells that are one cell-layer thick, though.
