  3. No alternation of generations
  4. Apical Meristems
  5. Paternally dependent embryos
  1. Alteration of Generations

All plants go through a sporic life cycle that is also called an “alternation of generations” life cycle

In alternation of generations the plant cycles through a “multicellular______gametophyte stage that produces ______, and a multicellular______sporophyte stage that produces ______”

 The ______produced in alternation are eggs produced in female structures called archegonia, while ______are produced in male structures called antheridia

Spores produced in alternation of generation are haploid cells that “germinate” and produce the multicellular haploid ______stage by the process of mitosis

In alternation of generations the haploid sperm cell and the haploid egg cell ______to produce the diploid zygote that develops into the multicellular diploid sporophyte stage through the process of mitosis

Haploid spores are produced in the ______by the process of meiosis
