hornwort การใช้

• The chloroplasts of some hornworts and algae contain structures called pyrenoids.
• The plant body of a hornwort is a haploid gametophyte stage.
• There are no moss or hornwort families endemic to New Zealand.
• Hornwort plants float in great numbers just under the surface.
• Liverworts, mosses and hornworts spend most of their lives as gametophytes.
• The Hornwort CCM was later characterized by Smith and Griffiths.
• The life of a hornwort starts from a haploid spore.
• Hornworts were traditionally considered a class within the division Bryophyta ( bryophytes ).
• Many hornworts develop internal mucilage-filled cavities when groups of cells break down.
• All other hornworts remain in the class Anthocerotopsida.
• Like other hornworts, its surface has stomata.
• In the mosses and hornworts a cuticle is usually only produced on the sporophyte.
• The three bryophyte clades are the Bryophyta ( mosses ) and Anthocerotophyta ( hornworts ).
• _Ceratophyllum demersum ( hornwort ).
• The sporophyte of most hornworts are also photosynthetic, which is not the case with liverworts.
• In either case, the protonema is a transitory stage in the life of a hornwort.
• In groups like liverworts, mosses and hornworts, the dominant generation is the sexual gametophyte.
• The thallus cells often contain more than one chloroplast, as opposed to other hornwort genera.
• Such colonies of bacteria growing inside the thallus give the hornwort a distinctive blue-green color.
• Evidence of multiple gains and losses of pyrenoids over relatively short geological time spans was found in hornworts.
