Content: This new diploid cell will divide through mitosis to eventually become the mature sporophyte. Keep in mind that the sporophyte is dependent upon the gametophyte for nutrition and support. The sporophyte actually grows within the archegonia. It will develop a foot that attaches to the gametophyte. A stalk will then grow out of the archegonia. At the end, a round capsule may be seen. The entire sporophyte structure can be seen here sticking out of the top of the dominant haploid stage. The parts of the sporophyte

The capsule contains sporangium, which produces spores. Within the sporangium are specific cells, sporocytes, that undergo meiosis to produce haploid spores. These spores are then released and will eventually become either a male or a female gametophyte, continuing the life cycle.
