Explanation:
The annulus of a moss capsule is a specialized structure that separates the operculum from the theca. The theca is the lower part of the capsule, while the operculum is the lid-like structure that covers the capsule.
The annulus is composed of specialized cells that are hygroscopic, meaning they can change their shape in response to moisture. When the moss capsule is dry, the annulus cells shrink and pull the operculum tightly against the theca, sealing the capsule. This helps to protect the spores inside from drying out.
However, when the moss capsule is exposed to moisture, the annulus cells absorb water and expand. This causes the annulus to change shape and push the operculum away from the theca, opening the capsule. This allows the spores to be released into the environment.
In summary, the annulus of a moss capsule separates the operculum from the theca. It plays a crucial role in regulating the opening and closing of the capsule in response to moisture levels.
