Detailed explanation-1: -A moss is a flowerless, spore-producing plant-with the spores produced in small capsules.

Detailed explanation-2: -The moss develops a spore capsule which is known as chlorenchyma. The chlorenchyma (contains chloroplast) cells help in assimilation and are parenchymatous (functional cells) which comprise chloroplast cells.

Detailed explanation-3: -The base of the seta is called the foot. The sporangium is the main body of the sporophyte and is the organ in which the spores are produced. As previously mentioned, most mosses will have a sporangium with these anatomical features: A sporogenous layer, a columella, peristome teeth, and an operculum.

Detailed explanation-4: -The gametophyte-derived stalk that raises the Sphagnum spore capsule is called a pseudopodium.

Detailed explanation-5: -Each sporophyte plant is composed of a capsule, which is the center of spore formation; a stalk; and a foot that attaches the sporophyte body to the tip of the gametophyte. Eventually, the diploid spores are released and, upon successful germination, grow into another moss plant.
