Plant cells? Algae? Coral? Were you right?
Surprisingly, these are leaf cells from a genetically engineered tobacco plant made to produce fluorescent proteins. Each squiggle shape is an individual plant cell with glowing proteins localizing to the cell periphery. Tobacco was the first genetically modified plant ever to be produced back in 1982, where DNA was altered so the plant became resistant to antibiotics. This was the first stepping stone for the production of all genetically modified crops today, a topic of intense debate in biology, economics, ethics, and government.
