Mosses reproduce using spores, not seeds, and have no flowers. Moss leaf under microscope, showing gemmae and a hair point (40x) Moss gametophytes have stems which may be simple or branched and upright (acrocarp) or prostrate (pleurocarp).
Annual growth increments can be found on the stem of this species of moss that resemble the rings of trees. [8] Pogonatum urnigerum does not specialize in asexual reproduction as it lacks gemmae cups and caducous structures that would help itself to asexually reproduce. However, it may asexually reproduce through fragmentation.
The bryophytes, which include liverworts, hornworts and mosses, can reproduce both sexually and vegetatively. The life cycles of these plants start with haploid spores that grow into the dominant form, which is a multicellular haploid gametophyte, with thalloid or leaf-like structures that photosynthesize. The gametophyte is the most commonly ...
They reproduce through vegetative propagation and reproduce sexually. Cross sections of the Elkhorn sea moss have a medulla composed of small thick-walled cells interspaced among large parenchyma cells. This moss is used for various types of foods that humans consume and can also be used to make a jelly-like dessert.
An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [2] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses (Bryophyta sensu lato).

To sexually reproduce, this moss utilizes the splash-cup mechanism to disperse the sperm it produces from its antheridia. The splash-cup mechanism occurs when raindrops splash onto the antheridia, collect sperm, and are hopefully splashed onto the female plant, where the sperm can swim to the archegonia. [14]
When a stem segment, called a pad, falls off, it can root and form a new plant. Leaves of some plants readily root when they fall off, e.g. Sedum and Echeveria. Fragmentation is observed in nonvascular plants as well, for example, in liverworts and mosses. Small pieces of moss "stems" or "leaves" are often scattered by the wind, water or animals.
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
