Hornworts are a group of bryophytes, or non-vascular plants, comprising the division Anthocerotophyta. The common name refers to the elongated horn-like structure, which is the sporophyte. The flattened, green plant body of a hornwort is the gametophyte plant.
Hornworts may be found worldwide, though they tend to grow only in places that are damp or humid. Some species grow in large numbers as tiny weeds in the soil of gardens and cultivated fields. Large tropical and sub-tropical species of Dendroceros may be found growing on the bark of trees.
The plant body of a hornwort is a haploid gametophyte stage. This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter. Each cell of the thallus usually contains just one chloroplast. In most species, this chloroplast is fused with other organelles to form a large pyrenoid that both manufactures and stores food. This particular feature is very unusual in land plants, but is common among algae.
Rob McCaw from Environment Canterbury is interviewed by Karin Stahel about why Hornwort is a pest plant, how to identify it and effective control methods.
Mosses, liverworts, and hornworts
Just showing and talking about hornwort an aquatic plant
Hank introduces us to nonvascular plants - liverworts, hornworts & mosses - which have bizarre features, kooky habits, and strange sex lives. 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 traces in our own reproductive systems.

Difference between liverworts and mosses . Major differences . , . . . . A 'difference between' reference site. Bryophyta, represent a group of plants that includes liverworts, hornworts and mosses growing predominantly in here are some more compilation of topics and latest discussions relates to this video, which we found thorough the internet. Hope this information will helpful to get idea in brief about this. The roughly , species of bryophytes are generally classified into three phyla, the bryophyta (mosses), jungermanniophyta (liverworts) and another difference between mosses and liverworts is with the sporophytes. Probably everyone who has seen a moss plant has also noticed little things that look like a seed pod on a stalk sticking out above the leaves. That thing is a '...
