Plant Life Cycles Showing the Alternation of Haploid and Diploid Generations

Charophytes (not in your lab manual)

Chara is a haploid plant that produces both motile sperm and non-motile eggs on the same plant in specialized multicellular structures.  After fertilization, a one celled diploid zygote is formed.  The zygote only divides by meiosis to make haploid spores.  It does not grow by mitosis to produce a multicellular diploid structure.
