Anthocerotophyta is a division of non-vascular plants commonly known as hornworts. These plants are characterized by their flat, green thalli that resemble leaves and their elongated sporophytes, which look like horns. Hornworts typically grow in moist environments and can be found in a variety of habitats, including soil, rocks, and tree bark. Hornworts are unique among bryophytes because they have a symbiotic relationship with cyanobacteria, which helps them fix nitrogen. They reproduce both sexually and asexually, with spores being produced in the sporangium of the sporophyte. This division plays a significant role in ecosystems by contributing to soil formation and nutrient cycling.
