Hornwort

Hornwort is a type of non-vascular plant that belongs to the division Anthocerotophyta. The name "hornwort" refers to the elongated horn-like structure, which is the sporophyte. Unlike mosses and liverworts, hornworts have a unique life cycle, and their sporophytes grow for a longer period.

Description

Hornworts usually grow on damp soils or on rocks in tropical and temperate environments. The thallus, which is the vegetative tissue of hornworts, is flat and green. The sporophytes, which are the reproductive structures, are long and horn-shaped, hence the name "hornwort".

Life Cycle

The life cycle of hornworts is characterized by an alternation of generations. The gametophyte stage is dominant and photosynthetic. The sporophyte stage grows from the gametophyte and remains attached to it. The sporophyte produces spores, which are released and grow into new gametophytes.

Taxonomy

Hornworts belong to the division Anthocerotophyta. There are about 100-150 species of hornworts in the world, divided into five families and twelve genera.

Uses

Hornworts are used in horticulture as soil conditioners and as a decorative element in gardens. They are also used in laboratory research, particularly in studies related to plant evolution and development.
