Detailed explanation-1: -In all plants, the sporophyte is a diploid multicellular plant body that produces haploid spores by meiosis. Sporophytes produce spores, just as gametophytes produce gametes.

Detailed explanation-2: -Funaria is moss and it belongs to the kingdom Bryophyta. Funaria keeps switching between the gametophytic division and sporophytic division phase. The capsule and seta belong to the sporophyte which undergoes meiosis to produce spores. Hence they are diploid (2n).

Detailed explanation-3: -This sporophyte remains attached to the gametophyte, which is similar to a parasite and is dependent on food and water, which divides by mitosis. The capsule contains spore-producing cells which undergo meiosis to form haploid spores.

Detailed explanation-4: -In mosses, the dominant stage is the haploid generation (the gametophyte). This means that the green, leafy gametophytic tissue is haploid (has only one set of chromosomes).
