The life cycle of bryophytes has two alternations of generations, one is haploid gametophyte generation and the other is diploid saprophytic generation. In both the life cycle, the bryophytes possess different morphology and physiological functions. Between these two alternations of generation, the haploid gametophyte phase lasts longer or dominates the diploid saprophytic phase. Gametophytes (male …
