The similarity and difference between mosses and ferns signs, features, table for grade 5

Both mosses and ferns can often be found nearby, and both of them belong to the type of primitive plants: mosses are the type of Bryophyta, and fern are considered pteridophyta. Both of these departments are considered to be a bending plants that do not have bones.

General features of mosses and ferns

If we talk about the similarity of the two departments, then the main one can, no doubt, consider their reproduction thanks to special organs (disputes). Do not forget that both mosses and ferns prefer to exist in a humid environment, and without it cannot.

Similar features of two detachments:

  • Both of them relate to primitive plants.
  • Both prefer to choose moist places provided by a sufficient level of shadow as a habitat, as they need moisture for fertilization (their spermatozoa contain flagella).
  • Both mosses and fern likes prefer to exist on the basis of other higher species of plants, although they do not belong to parasitic forms, since they produce their nutrition thanks to photosynthesis.
  • Both can be ranked to unheard of and dishonest species.
  • These two detachments are distinguished by global changes in generations.
  • These plants are sporeforming.
  • Both those and others contribute to the prevention of such a phenomenon as soil erosion.
  • Distinctive features of mosses and ferns

    The differences between mosses from fern include:

  • If the mosses have no root system, then ferns are equipped with a large number of subordinate roots that grow from a modified shoot.
  • The foliage of mosses is microscopic, but vayi fern have a difficult structure.
  • The gametophyte in mosses is an adult plant, and in fern is an embryo for this purpose.
  • Fern are customary to be attributed to diploid forms, and mosses are haploid.
  • The process of photosynthesis in the mosses is quite inhibited, but, nevertheless, they can calmly do this under the snow, and if the ambient temperature is not lower than 0 s, then mosses usually remain evergreens.
  • Today, mosses are in a kind of evolutionary impasse and cannot multiply without liquid.
  • Mosses differ in poorly differentiated fabrics, but in porvertents, on the contrary, fabrics are distinguished by specialization.
  • In mosses, the cycle of their development is associated with gametophytes and sporophytes, but ferns and their sexual generation are an independent plant.
  • Mosses are able to lead to soil.

    Signs Mojshaped (mosses) Paporotnikshaped (fern)
    Features of autonomic organs Have a primitive escape, there are no real roots, they are attached to the soil of risoids, consisting of the same cells and devoid of conductive tissue The powerful development of various leaves is characterized by two functions spore formation and photosynthesis. Liszt-Vaya has an apical growth attached to a shortened stem that turns into a well-developed rhizome
    Features of the tissue organization There is an assimilation fabric, as well as weakly expressed, mechanical, stocking and integumentary fabrics. There is no conductive fabric Well developed assimilation, mechanical fabric. The stem has a welldeveloped conductive fabric, the xylem is represented by tracheids, the Floem sieve cells
    The prevailing generation Gametophyte Sporophyte
    What is represented by the sporophyte (asexual generation) in the modern flora Box on the leg Leafstable rhizome herbaceous plant. In the tropics woody plant
    The place of education spores Sporangi, located

    In the box

    Sporangia collected in the Sorouses on the Vaiy (leafstag)
    What is the sexual generation (gametophyte) Leafstable plants with archegonia and anteriadia (in green mosses separately, in whites bisexual) Green, heartshaped embryos with archegonia and anteriadia; more often bisexual, but there may be separate. Size 1-5 mm
    The life expectancy of sexual

    generations (gametophyte)

    Many years One season
    The position of the sporophyte in relation to the gametophyte On one plant, the sporophyte is attached to the gametophyte, completely depends on it and eats at its expense Different plants
    Position in evolution Dlue branch Progressive direction that gave seed plants
