Natural symmetry in this one-celled desmid alga

May 2017 (approx.)

Detailed Description

Some single-celled green algae in the desmid family are symmetrical, with two halves joined by a bridge containing the cell’s nucleus. USGS biologist Barry H. Rosen and colleagues have been sampling desmids in Florida’s Loxahatchee National Wildlife Refuge for more than a year.
