Moss anatomy,artwork. Mosses are bryophytes,plants that do not have a vascular system and reproduce via spores rather than flowers and seeds. Unlike most plants the multicellular phase of the plant,the gametophyte,contains one set of chromosomes rather than two (it is haploid). The sporophyte,which grows from the gametophyte,contains two of each chromosome (it is diploid). It consists of stalks (setae) topped with capsules. The cells within the capsules undergo meiosis (nuclear division) to form the haploid spores,the reproductive cells | |
