Answer
The haploid choices are:* **Antheridium:** The antheridium is the male reproductive structure in bryophytes and some other plants. It produces haploid sperm.* **Archegonium:** While the archegonium itself is part of the haploid gametophyte, the egg cell *within* it is also haploid.* **Egg cell:** Egg cells are gametes and are always haploid.* **Gametophyte:** The gametophyte is the haploid, gamete-producing phase of the plant life cycle.* **Protonema:** The protonema is the thread-like chain of cells that forms the earliest stage of the gametophyte in mosses. Since it's part of the gametophyte, it's haploid.* **Spermatozoid:** Spermatozoids (or sperm) are gametes and are always haploid.
