Recent studies suggest that stomata in hornworts are involved in sporophyte dehydration and spore dispersal (Renzaglia et al., 2017; Pressel et al., 2018). Stomata develop at the base of …

Hornworts have a flattened thalloid gametophyte, out of which grow their long photosynthetic sporophytes (Figure \(\PageIndex{1}\)), composed of a sporangium with a columella and …

2024年11月23日 · However, liverworts develop a small sporophyte, whereas hornworts develop a long, slender sporophyte. Liverworts also disperse their spores with the help of elaters, while …

2024年6月11日 · Sporophyte (diplophase): The diplophase starts with fertilized egg or zygote. It has diploid number of chromosomes. The zygote undergoes cell division and differentiation to …

Hornworts differ from other bryophytes in having a region of continuous growth at the base of the sporophyte, and a large irregular foot. The stalk that attaches the foot to the spore-bearing …

2020年8月13日 · Like other bryophytes, the hornwort sporophyte is matrotrophic, meaning it develops on and is nourished by the gametophyte. Unlike other plants, the sporophyte grows …

Hornworts, phylum Anthocerotophyta, are have thalloid gametophytes with monoplastidic cells. Their sporophytes are composed of a long, thing sporangium that grows from a basal meristem.

Hornwort sporophytes are unusual in that the sporophyte grows upward from meristemic tissue near its base, instead of from meristemic tissue near its tip as in the common pattern of plant …
