The correct answer is option C...Because Apophysis is basal sterile portion of capsule in continuation with seta.In capsule, the funaria stomata present only in Apophysis.

Apophysis of moss is the lower part of the capsule. It is a specialized structure that supports the capsule and helps in the dispersal of spores. The structure of the apophysis varies among different moss species and is an important characteristic used for their identification.

Structure of Apophysis
The apophysis is a thickened region at the base of the capsule, which is differentiated from the rest of the capsule by its color, shape, and texture. It is composed of cells that are modified to perform specific functions. The structure of the apophysis includes the following parts:

1. Sterile cells: These cells are present at the base of the apophysis and help in anchoring the capsule to the gametophyte.

2. Conducting cells: These cells are responsible for the transport of water and nutrients from the gametophyte to the capsule.

3. Photosynthetic cells: These cells are present in some species of moss and help in the production of food through photosynthesis.

Function of Apophysis
The apophysis plays an important role in the life cycle of moss by facilitating the dispersal of spores. When the capsule is mature, the cells of the apophysis undergo cell death, causing the capsule to rupture and release the spores into the air. The shape, texture, and color of the apophysis are important characteristics used to identify different species of moss.

In conclusion, the apophysis is a specialized structure in moss that supports the capsule and helps in the dispersal of spores. Its structure and function vary among different species of moss and are important characteristics used for their identification.
