Which of the following describes bryophytes?

Bryophytes are defined as nonvascular plants, which distinguishes them from other plant groups that possess vascular tissue. This nonvascular characteristic means that bryophytes lack specialized structures for transporting water and nutrients, such as xylem and phloem, that are found in vascular plants. Because of this, bryophytes also tend to be small and are often found in moist environments where water is readily available.

Moreover, bryophytes generally do not have many of the adaptations seen in more complex plant groups, such as roots, stems, and leaves in a true sense, or the ability to develop effective methods for water conservation. Their life cycle also demonstrates a prominent gametophyte stage, which is a noteworthy aspect of their biology.

The other options do not accurately reflect the characteristics of bryophytes. For instance, the mention of vascular plants with flowers refers to angiosperms, while ferns and conifers are representative of vascular plant groups. Additionally, while some bryophytes may be found in aquatic environments, they are not limited to this habitat and can thrive in various moist terrestrial habitats.
