What are the three phyla/divisions of structurally rather simple terrestrial plants that encompass the small group of bryophytes

(marchantiophyta(liverworts), Anthocerophyta(hornworts) and Bryophyta(true mosses)


How are the three phyla of bryophytes similar (marchantiophyta(liverworts), Anthocerophyta(hornworts) and Bryophyta(true mosses)

-They have no specialized tissues such as conducting or supporting tissues.
-They exhibit alteration of heteromorphic generations, with a haploid and diploid generation
-their sporophytes are dependent on the gametophytes and bear only a single sporangium
-The gametophyte is the long lasting (dominant) generation/life form
-require water for fertilization and therefore often low- growing in moist places
-has both archegonia and antheridia on gametophyte


What are the two groups that liverworts can be divided into?

The thallose (non-leafy) liverworts and the Leafy liverworts
-marchantia= thallose liverwort


What is a thallus?

Ribbon-like dichotomously branching body with a midrib region in the middle/centre of the ribbon (how the gametophyte grows)


What are the two classes of Moss that we look at

The Bryidae(The true mosses) and Sphagnum(The peat Mosses)
*didnt look at granite moss


What are the three divisions of seedless vascular plants we examine in lab

Lycophyta(club mosses&spike moss), Sphenophyta(horsetails) and pterophyta(ferns)


What are the two sp of the phyla lycophyta(fake mosses) that we look at *seedless vascular

-lycopodium(club moss) and Selaginella(spike moss)

*isoetes(quillworts) are also a sp of lycophyta but not thoroughly discussed
