The sporophyte of a bryophyte is the diploid generation of the plant's life cycle. It is typically dependent on the gametophyte for nourishment and support. Here are the parts of a bryophyte sporophyte:

* Foot: This structure attaches the sporophyte to the gametophyte, drawing nutrients from it.

* Seta (stalk): This slender stalk supports the sporangium, elevating it above the gametophyte.

* Sporangium (capsule): This structure contains the sporocytes which undergo meiosis to produce spores.

* Calyptra: In some bryophytes, a protective cap called the calyptra covers the sporangium. This is derived from the gametophyte.

It's important to remember that the sporophyte is the diploid generation in the life cycle of bryophytes, meaning it contains two sets of chromosomes. The gametophyte, the dominant generation in bryophytes, is the haploid generation, meaning it contains only one set of chromosomes.
