Non vascular Plants By Sean McCaffrey and Natalie Hamilton

Non vascular plants are plants that do not have a vascular system, but hey might have simple tissues that transport water around the plant. Bryophytes include all non vascular plants which includes liverworts, mosses, and hornworts.

One group of non vascular plants is the phylum hepatophyta which is the liverworts. These plants mainly live in moist environments and they need water from dew and other water sources to be able to reproduce. The structure of the plant is simple they lack vascular tissue like xylem and phloem.

The next group of non vascular plants are the phylum bryophyta which is the mosses. These plants are small and often do not stand out in their surroundings.They have no vascular tissue or wood to give them structural support, nor do they have large leaves or flowers or cones. The mosses help stop erosion near water they help recycle nutrients in environments like the tropical rain forest. Finally mosses assist with insulating the arctic permafrost.

Phylum anthocerophyta is another group and they are the hornworts. The plant body of a hornwort is a haploid gametophyte stage. This stage usually grows as a thin rosette or ribbon-like.The Anthocerotophyta are characterized by their long, horn-shaped sporophyte, from which they get their name “hornworts”. The colonies of bacteria that live the thallus of hornworts are what give it, it's distinct blue green color. Hornworts might also have slime pores which is similar to the stomata of other plants.
