The thermoluminescence activity of the resurrection fern increased as it was exposed to six separate but consecutive flashes of green safelight at its leaves. Because thermoluminescence from the fern fronds wasn’t observed until higher temperatures, this hints that the fern’s chloroplasts may have a mechanism to withhold and store energy for the fern as it desiccates that allow it to survive higher temperatures and extreme periods of desiccation. Reproduction The fern has spores on the bottom of the fronds, contained in sori. The fern sporulates in Summer and early Fall. Rhizome sections are also viable offspring and can root themselves in new medium.
