| Structures resembling stems, roots, and leaves are found on the gametophore of bryophytes, while these structures are found on the sporophytes in the vascular plants. |
| Sporophytes of mosses usually consist of the foot, which penetrates the gametophore, the seta, with an internal conducting system, and a terminal sporangium. |
| This sporeling is rich in chlorophyll and soon forms an apical cell from which the gametophore grows. |
| A single mat of protonemata may develop several gametophore shoots, resulting in a clump of moss. |
| When specific concentrations of the hormones are reached, the branches of the protonema generate small buds, which in turn produce the leafy gametophore. |
