	<p>Hornworts are theorized to be one of the earliest groups of evolved land plants. They are suggested to have descended from algae species, roughly 500 million years ago. They have characteristics that suggest they evolved in primitive conditions, such as the lack of vascular tissues. Understanding the evolution of hornworts has played a significant role in the understanding of the colonization of land by plants. It is suggested that this is an early predecessor of vascular land plants, and branched off very early in the evolution of plants [3]. <p>		<p>Hornworts are theorized to be one of the earliest groups of evolved land plants.

	<p>Hornworts belong to the division Anthocerotophyta, which is one of the three divisions of non-vascular land plants.

There are constantly new discoveries, as this particular plant is understudied.<p>		<p>Hornworts belong to the division Anthocerotophyta, which is one of the three divisions of non-vascular land plants.

	Hornworts have been used in traditional medicine for skin irritation, antibiotics, and wound healing. There has even been research done on their possible anti-cancerous properties~~[5]~~. They also have ecological significance, contributing to soil formation and [[Nutrient Cycling\|nutrient cycling]]. In scientific research, hornworts are used as model [[organisms]] to research properties of plant biology, and evolution, as they have remained almost entirely unevolved for 500 million years.

	The fertilized egg develops into a sporophyte, which is the horn-like structure that emerges from the gametophyte. The sporophyte produces spores through meiosis. The spores are released and under the right conditions will produce more gametophytes[6].</li>		The fertilized egg develops into a sporophyte, which is the horn-like structure that emerges from the gametophyte.

	==Characteristics==		==Characteristics==

	Hornworts have a flattened, thalloid gametophyte body, which has smooth rhizoid anchors to allow the plant to persist on many different surfaces, such as [[soil]], rocks, and bark. They lack seeds, true roots, stems, and leaves, which characterises them as brophytes. They have an alternating life cycle with a haploid and diploid phase.The diploid sporophyte grows from the gametophyte and is characterized by an ascending horn-like structure. The gametophyte is characterized by a lobed or wrinkled, green colored sheet (thallus), which contains only 1-2 chloroplasts per cell, compared to liverworts and mosses which can have many chloroplast per cell. Hornworts produce mucilage cavities throughout every cell. ~~Their~~ is no differentiation in the composition of the thallus of a hornwort, unlike the liverworts, which have different cells performing different functions within their thalli [2].
