Bryophytes include all the land plants. Evolutionary studies have shown that all the bryophytes might have originated from a common green algae. A sporophyte can be described as a diploid multicellular stage which is common in all plants and algae. Hence, we can infer that the multicellular sporophyte generation was common in all bryophytes and hence can be seen even today.
