The stinkmoss species Splachnum sphaericum develops insect pollination further by attracting flies to its sporangia with a strong smell of carrion, and providing a strong visual cue in the form of red-coloured swollen collars beneath each spore capsule. Flies attracted to the moss carry its spores to fresh herbivore dung, which is the favoured ...
In Common Smoothcap moss (Atrichum undulatum), the vibration of sporophyte has been shown to be an important mechanism for spore release. [ 15 ] In the case of spore-shedding vascular plants such as ferns, wind distribution of very light spores provides great capacity for dispersal.
Moss sporangia (the capsule and the stalk/seta make up the diploid asexual sporophyte generation) [6] In mosses, liverworts and hornworts, an unbranched sporophyte produces a single sporangium, which may be quite complex morphologically.
The powder consists of the dry spores of clubmoss plants, or various fern relatives principally in the genera Lycopodium and Diphasiastrum.The preferred source species are Lycopodium clavatum (stag's horn clubmoss) and Diphasiastrum digitatum (common groundcedar), because these widespread and often locally abundant species are both prolific in their spore production and easy to collect.
In mosses, the gametophyte is the dominant generation, while the sporophytes consist of sporangium-bearing stalks growing from the tips of the gametophytes Sporophytes of moss during spring In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and embryo sac
Mosses are fascinating and ancient plants with unusual lifestyles compared to the leafy plants with which folks are familiar. Being very small, tolerant of shade, and spreading via spores, they ...
The spores of lycopods are highly flammable and so have been used in fireworks. [30] Lycopodium powder, the dried spores of the common clubmoss, was used in Victorian theater to produce flame-effects. A blown cloud of spores burned rapidly and brightly, but with little heat. (It was considered safe by the standards of the time.) [citation needed]
Protonemata are characteristic of all mosses, are present in some liverworts under certain conditions [2] but are absent from hornworts. [ citation needed ] The protonemata are composed of two cell types: chloronemata , which form upon germination of the spore, and caulonemata , which later differentiate from chloronemata under the influence of ...
