This was long before plants helped make earth the liveable planet we know today. [10], Thermoluminescence of the resurrection fern has been tested to observe at what temperatures it occurs and therefore shows what temperatures and amount of desiccation the ferns can tolerate before their chloroplasts lose the energy they’ve stored for the plant, in the form of light emissions. The fern fronds contain canal cells in the center of their surface scales that direct water to the epidermis of the fern leaves, allowing absorption. 19 18 3.
