This strategy is, however, more widespread in mosses. Because most vascular epiphytes are homoiohydrous (i.e., relatively desiccation intolerant), other adaptive strategies are needed in order to avoid dehydration, to limit water loss and/or to store water. According to their tolerance level to...
Ferns are vascular plants that lack f lowers and are remarkable among plants in having two alternating free-living generations, called gametophytes and sporophytes. Mosses, gymnosperms and angiosperms (seed plants) also have alternating generations, but these are not both free-living. In mosses and...
It is evolutionary advantageous to be a vascular plant because: A. They require less resources than non-vascular plants. B. Fertilization always relies on water, which is abundant on earth. C. They have a single large sporangium...
However, their fossil record is scarce because of the low preservation potential of the delicate, membranous laminae. So far, no Hymenophyllaceae fossils have been reported from tropical Asia. Here, we describe some fern remains and their syninclusions (spike-mosses) in four pieces of Kachin ...
