1

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)

2

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

3

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

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

4

What is a thallus?

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

5

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

6

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

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

7

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
