Life Cycle Of Nonvascular Plants
The life cycle of nonvascular seedless plants can be described as follows. The familiar green photosynthetic moss plants are gametophytes.

They are the only plants with a life cycle in which the gametophyte generation is dominant.
Life cycle of nonvascular plants. The familiar green photosynthetic moss plants are gametophytes. They have no flowers leaves roots or stems and cycle between sexual and asexual reproductive phases. Nonvascular plants include mosses liverworts and hornworts.
Figure below shows the life cycle of moss. The sporophyte generation is very small and dependent on the gametophyte plant. The sporophyte tends to be much taller than the gametophyte extending a tall stalk upwards so that the spores it produces can be carried by the wind.
Life Cycle of Nonvascular Plants. Lifecycle of a Nonvascular Plant. Non-vascular plants or bryophytes are plants that lack a vascular tissue system.
Members of these groups which live in both marine environments and on land are considered a nonvascular plant. Life Cycle of Nonvascular Plants. In this cycle a gametophyte gives rise to gametes.
Therefore nonvascular plants tend to live in moist environments. This life cycle is similar to those of the liverworts. Figure 11 Life cycle of a non-vascular plant.
The gametophyte is a haploid organism containing only one set of DNA. Nonvascular plants inherited their reproductive cycle from algae but have perfected it to the point where it is now used by all plants in one way or another and has even left. The plant body in which the true.
The life cycle of nonvascular plants involves the alternation of generation between the gametophytic phase and the sporophytic phase. The sporophyte portion of the life cycle appears infrequently and is attached to the gametophyte. Nonvascular plants include mosses liverworts and hornworts.
Figure below shows the life cycle of moss. 4 rows Nonvascular plants include mosses liverworts and hornworts. The gametophytic phase is the haploid generation and the sporophytic phase is the diploid generation.
In this cycle a gametophyte gives rise to gametes. All plants and some algae exhibit an alternation of generations life cycle. The gametophytic phase is the prominent phase whereas the sporophytic phases depend upon the gametophytic phase.
The familiar green photosynthetic moss plants are gametophytes. The conspicuous dominant phase of the life cycle of these plants is the gametophyte haploid generation. Nonvascular plants include mosses liverworts and hornworts.
Hank introduces us to nonvascular plants - liverworts hornworts mosses - which have bizarre features kooky habits and strange sex lives. Figure below shows the life cycle of moss. They are the only plants with a.
The life cycle of a typical moss is illustrated below. They are the only plants with a life cycle in which the gametophyte generation is dominant. For this reason sexual reproduction must happen in the presence of water.
The primary divisions of bryophytes include Bryophyta mosses Hapatophyta liverworts and Anthocerotophyta hornworts. The gametophyte is a haploid organism containing only one set of DNA. Gametes are formed in specialized structures on the gametophyte called antheridia containing male gametes and archegonia containing female gametes.
Lifecycle of a Nonvascular Plant All plants and some algae exhibit an alternation of generations life cycle. They are the only plants with a life cycle in which the gametophyte generation is dominant. The sporophytegeneration is very small and dependent on the gametophyte plant.
The male gametophyte produces flagellated sperm that must swim to the egg formed by the female gametophyte.
