  2. 1.1 Domain Eukarya : Kingdom Plantae • Describe alternation of generation as the unique characteristic of Plantae • State the classification of Plantae into four groups • State the classification of bryophytes into three divisions/phyla • State the classification of pteridophytesinto two divisions/phyla • State the classification of gymnosperm into four divisions/phyla

  3. Unique Characteristic of Plantae : Alternation of Generation Occurs in the life of plants, where gametophyte (n) generation alternateswith the sporophyte (2n) generation. Sporophyte generation produce spores by meiosis Gametophyte generation produce gametes by mitosis
