Botanical, mosses are bryophytes, or not-vascular plants. They can be distinguished from liverworts similar (Marchantiophyta or the apparently hepatic) from multicellular theirs rhizoids. Other differences are not universal for all mosses and all the liverworts, but the presence "of the stem" clearly differentiated and "of the sheets", the lack of sheets deeply lobed or segmenta you and the absence of the sheets organizes to you in three troops, all the point to the plant that is a moss. The greater part of the kinds of plants has a double part of the chromosomes in they cells (diploidi, that is every chromosome exists with an associate who contains the same genetic information) while mosses (and others bryophytes) has only a single one with of the chromosomes (aploidi, that is every chromosome exists in one only copy to the inside of the cell). There are periods in the lifecycle of moss when they have with suit and coupled of the chromosomes but this it is only during the phase of the sporophyte. The life of a moss begins from a spora aploide, that it germinates in order to produce a protonema, that filament mass is one or thalloid (slowly and thallus-as). That is one transitory phase in the life of a moss. From the protonema it develops to the gametophore ("carrying gamete-element") that it is differentiated in the stems and the sheets (' microphylls). From the tips of the stems or coppers developments the organs of the sex of mosses. The organs of the female are known like archegonia (songs the archegonium) and are protect from a group of the sheets modified known like the perichaetum (plurale, perichaeta). The archegonia it has necks calls to you venters which the sperm male swims down. The organs maschii are known like antheridia (singular antheridium) and are enclosed from the modified sheets call the perigonium to you (plurale, perigonia). Mosses can be dioicous (confront dioecious in the plants of the seed) or monoicous (confront monoecious). In mosses dioicous, it is maschii that in the feminine organs of the sex they are the different plants regarded of the gametophyte. (also called autoicous) in mosses monoicous, are regarded the same plant. In water presence, the sperm from the antheridia swims to the archegonia and the fertilization happens, leading to the production of one sporophyte diploide. The sperm of mosses is biflagellated, that is has two flagellates that they help in the propulsion. Since the sperm must swim to the archegonium, the fertilization cannot happen without water. After fertilization, the sporophyte sour it pushes the relative escape from the Venter archegonial. It takes approximately a quarter to the half of year affinchè a sporophyte you make to mature. The body of the sporophyte contains a long stem, called a silk and a cap covered from a protection has called the operculum. The cap and the operculum alternatively are inguaina you from a calyptra aploide who is the remains of the Venter archegonial. The calyptra it falls from usually when the cap is mature. To the inside of the cap, spora-producing the cells endure aploidi the meiosi in order to form the spore, on which the cycle it can still begin. The mouth of the cap usually is anellata from with of the teeth calls to you peristome. That can be absent in some mosses. Mosses have been group to you with liverworts and the hornworts traditionally in the Bryophyta division (bryophytes), to the inside of which mosses they have composed the code Musci category. This group, however, is paraphyletic and hour stretches to being scisso. In a such system, the Bryophyta division refers to mosses specifically. More neighbors of the vascular plants seem to be the living relatives. The Sphagnopsida, torba-mosses, contains the two living kinds Ambuchanania and Sphagnum, therefore like the fossil rates. These great mosses form the immense silicee swamps in the swamps of the torba. The sheets of Sphagnum have great out of order cells to alternate themselves with the fotosintetiche cells living. The out of order cells contribute to store the water. Beyond to this character, the only ramification, protonema (and slowly expanded) of the thallose and explosive to break off the place of the sporangium it beyond to other mosses. Polytrichopsida has sheets with the lamelle, that they are you strike yourself on the sheets that are similar the fins on a heat dissipator. These help in order to maintain it the humidity. They differ they give from other mosses in detail others of their development and anatomy also and can also become larger as an example of the greater part of other mosses, with the common one of Polytrichum that form the shocks-absorber until the high of 40.cm (16.in). Moss of the higher earth, a member of the Polytrichidae is supposed of being arrogant of Dawsonia, native in New Zeland and Australia. Wherever they happen, mosses demand the small humidity to survive because of format and thinness of the woven ones, the lack of cuticola (covering cereo in order to prevent to loss of water) and the necessity for liquid water to complete the fertilization. Some mosses can survive dissecazione, sending back to the life in some hours of the rehydration. In the Nordic latitudes, the side of the north of the trees and the cliffs will have generally more moss in average that other sides (benchè the outcroppings of the south-side are not disowned). That is presupposed for being because of the sufficient water lack for the reproduction from the side of the sun-coverings of the trees. The south of the Equator the inverse one is to align. In deep forests in which the solar light it does not penetrate, mosses develop themselves equally well from all sides of the log of the tree. Moss is considered a erbaccia in the prati ones of the grass, but deliberately it is advised to develop itself under the principii aesthetic exemplifies to you making the giardinaggio of the Japanese. In old the garden of the tempiale, moss can cover one scene with the carpet of the forest. Moss is believed in order to add a sense of calm, the age and stillness to one the scene of the garden. The cultivation rules are wide not established. The collections of moss are begun enough often using the champions transplant to you from the wild one in a bag diritegno. However, the specific species of moss can be extremely difficult to carry out via from their natural places with their only combinations of light, humidity, the shelter from wind, etc. Increasing moss from the spore still less is controlled. The spore of moss falls in one constant rain on the superficial ones exposed; those superficial ones that is accommodate them to one determined species of moss will be colonized typically from that moss within some years of exposure to wind and rain. The materials that are porosi and humidity try again to you, which the mattone, wood and determined concrete mixtures of principle is accommodates them to moss. The superficial ones can also be prepared with the silicee substances, comprised latticello, yogurt, urine and delicately puréed the mixtures of the champions of moss, the water and the composed one ericaceous. A fad passing for the moss-collection towards the end of the nineteenth century it has lead to the institution of mosseries in much garden British and Americans. The mossery it is constructed typically from wood to sticks, with a flat roof, opens to the side of the north (carrying out tonality). The moss champions have been install to you in the leaks between the wood sticks. The mossery entire then inumidito regularly in order to carry out the development. There is a remarkable market of mosses re-united from the wild one. The uses for intact moss are mainly in the florist trade them and for the domestic decoration. Moss to decay in the Sphagnum kind is moreover the main member of torba, that "use as combustible is extracted", as additive orticolo of the land and in malto smoking in the production of whisky Scottish. Moss of Sphagnum, generally the cristatum of species and the subnitens, is collected while still it grows and it is dried for being used in maternal schools and horticulture like plant that grows medium. The practical one of collection of moss of the torba would not have to be confused with the collection of the torba of moss. Moss of the torba can be collected on a sostenibile base and to be controlled in fashion to allow the regrowth, while the collection of the torba of moss is generally considered to cause damages acclimatizes meant them to you while the torba it is put to knot with little or no probability of the recovery. In rural United Kingdom, the antipyretica of Fontinalis has been used traditionally in order to extinguish fires poichè could be found in remarkable amount in rivers dispostamento and moss has maintained the great water volumes that have contributed to extinguish flames. This historical use is reflected in the relative specific name of Latin/Greek, the approximate meant one of which is "against fire".

Melissa moss
The Melissa from his father excepts the Zeus inside greek mythology and it is a name of grudge and the Cronus of Dob n nymph. She will be wrong hided inside the hill and in him she fed the milk from the Amalthea and the honey. When the Cronus discovers this, he went round her with the insect. After it does not change her from the insect shape where the force comes in by the Zeus, he changed her, with the queen bee.
