Moss Labeled Diagram | Anatomy and Structure

Capsule – The capsule is the part of the moss that produces and releases spores.
Operculum – The operculum is a small lid that covers the capsule and protects the spores inside.
Peristome Teeth – The peristome teeth are small structures around the opening of the capsule that help control the release of spores.
Sporophyte – The sporophyte is the structure that produces spores through meiosis. It consists of a seta (stalk) and a capsule.
Gametophyte – The gametophyte is the main body of the moss and is responsible for producing gametes through mitosis. It consists of a stem-like structure called a protonema and leafy structures called gametophores.
Rhizoids – Rhizoids are small, hair-like structures that grow from the base of the gametophyte and anchor it to a substrate. They also absorb water and nutrients from the environment.
Protonema – The protonema is a mass of green, thread-like cells that develops from the spores and eventually grows into the mature gametophyte.
Leaf – The leafy structures on the gametophore are called leaves. They are small and simple, with a single vein running down the middle.
Stem – The stem is the main structural support of the gametophyte and is responsible for transporting water and nutrients between the rhizoids and the leaves.
