Do Bryophytes Have Stomata?

Stomata in bryophytes are located on sporangia and are restricted in their occurrence across phylogeny. Liverworts are the only extant land plants that lack stomata entirely, while stomata are widespread but not ubiquitous in hornworts and mosses.

Do bryophytes have stomata and cuticle?

Openings that allow the movement of gases may be observed in liverworts. However, these are not stomata because they do not actively open and close. The plant takes up water over its entire surface and has no cuticle to prevent desiccation.

Does a moss have a stomata?

Most mosses and hornworts, but not liverworts, possess stomata on their sporophytes (Chater et al., 2017; Merced and Renzaglia, 2017; Duckett and Pressel, 2018; Brodribb et al., 2020).
