Most mosses have capsules that open at the top. We test the hypothesis that evolution of sporangium (capsule) shape of the mosses-the second most diverse land-plant lineage-has been driven by differing physiological demands of life in diverse habitats. Surrounding the spore sacs, there are large numbers of air cavities, which are separated from one another by trabuculae. Looking down on it, the Common Hair Cap Moss has a star shaped appearance because of the pointed leaves arranged spirally at right angles around a stiff stem (3). Inside the capsule, spores divide by meiosis, mature, and are shed by wind currents and breezes. Please enable it to take advantage of the complete set of features! 210, 3; 211, 6). Sporophyte setae are weak and transparent; and when mature the capsule explodes, shooting off its lid (operculum) and spores with an audible “pop.” Sphagnum moss is estimated to cover about 1 percent of the earth’s surface, an area half the size of the United States. In addition, we examine the association between shifts in sporangium shape and species diversification. You can specify conditions of storing and accessing cookies in your browser. B. Likewise with the size possessed by the smallest moss is generally ranged between 1-2 cm, and most of the high about 20 cm. doi: 10.1371/journal.pone.0187228. We demonstrate that sporangium shape is convergent, under natural selection, and associated with habitat type, and that many shifts in speciation rate are associated with shifts in sporangium shape. Moss Structure. What is the shape of moss capsule?

Here, sea moss benefits and side effects, according to experts. We reconstruct ancestral sporangium shape and ancestral habitat on the largest phylogeny of mosses to date, and use phylogenetic generalized least squares regression to test the association between habitat and sporangium shape. The sporangium, a spore-bearing structure, contains minute, developing spores and is attached to the seta by a structure called a foot. Mosses alternate between diploid and haploid generations in their life cycle, which is unique among flowering plants. C. 1.
