Bryophytes in Raven Biology of Plants

These flashcards cover key vocabulary and essential concepts related to Bryophytes as discussed in the Raven Biology of Plants lecture.

Bryophytes

A group of non-vascular land plants, which include mosses, liverworts, and hornworts.

Gametophyte

The dominant and haploid generation in bryophytes that produces gametes.

Sporophyte

The diploid generation in bryophytes that is dependent on the gametophyte and produces spores.

Rhizoids

Root-like structures in bryophytes that anchor the plant but are not true roots.

Antheridia

The male gametangia in bryophytes that produce sperm.

Archegonia

The female gametangia in bryophytes that contain the egg.

Sphagnum moss

A type of peat moss known for its water-holding capacity and antibacterial properties.

Alternation of generations

The life cycle of plants where the haploid gametophyte and diploid sporophyte alternate.

Hydroids and leptoids

Water- and food-conducting cells in mosses, respectively.

Liverworts

Bryophytes belonging to the phylum Marchantiophyta, characterized by their thalloid structure.

Hornworts

Plants of the phylum Anthocerophyta with horn-shaped sporophytes that have stomata.

Sphagnum

A key genus of mosses that forms peat and is used as a soil amendment.

Calyptra

A covering over the sporangium in bryophytes that falls off prior to spore dispersal.
