: a division of nonflowering plants comprising the mosses and liverworts characterized by rhizoids rather than true roots, by little or no organized vascular tissue, by multicellular archegonia and antheridia in which only some of the cells are sporogenous, and by a clear-cut alternation of generations, the sporophyte …

What are two characteristics of bryophytes?

Bryophytes are an informal division that consists of 3 groups of non-vascular plants, namely mosses, liverworts, and hornworts. Prominent bryophytes characteristics are the absence of true roots stems and leaves. Furthermore, rhizoids perform the function of roots, essentially anchoring the plants into the surface.

Where are bryophytes found?

Bryophytes are regarded as transitional between aquatic plants like algae and higher land plants like trees. They are extremely dependent upon water for their survival and reproduction and are therefore typically found in moist areas like creeks and forests.

Can bryophytes reproduce asexually?

Asexual reproduction s. l. and the formation of asexual diaspores therefore is a remarkable feature and widespread in bryophytes. In nearly no other plant group asexual reproduction is so important than in bryophytes. A great number of bryophyte species, especially dioicous ones, reproduce exclusively asexually.

Gymnosperms are non-flowering plants belonging to the sub-kingdom Embophyta. The seeds are not enclosed in an ovary or fruit. They are exposed on the surface of the leaf-like structures of the gymnosperms. They can be classified as Coniferophyta, Cycadophyta, Ginkgophyta and Gnetophyta.

Why Hornworts are so called?

The reason they are called hornworts is because of their reproductive structures or “sporophytes.” Similar to their moss and liverwort cousins, hornworts undergo an alternation of generations in order to reproduce sexually.
