Phylum Bryophyta pp. 451-454

Similarities to Algae: Non-vascular Display alternation of generations Need water for reproduction

Appearance/Structure: Less than a few centimeters tall Rhizoids = rootlike Leaflets = moss “leaves”, no stem, no protective layer Seta = stalk Sporangia = capsule containing spores

Lack Adaptations For Water-free Existence: Lack conductive tissue instead water passes from cell to cell by osmosis & surface tension around the stalk Lack cuticle Lack true roots Have sperm which need to swim to egg

Ecological Role: Primary producer Pioneer species Can grow on rock & inhabitable soil Moss dies & creates enriched soil for other, more complex plants to colonize

IMPORTANT CHARACTERISTICS OF MOSSES! Reproduction: Alternation of Generations Gametophyte Haploid (n) Has sexual reproduction requiring water Dominant stage Sporophyte Diploid (2n) Has asexual reproduction using spores Dependent on the gametophyte IMPORTANT CHARACTERISTICS OF MOSSES!
