The middle part of funaria capsule is sterile is known as -a)Columella...
Funaria capsule is a sporangium that contains spores. It consists of three parts: the apophysis, the capsule wall, and the operculum. However, the middle part of the capsule is sterile and is known as the columella.

Explanation:

- Funaria is a type of moss that has a capsule for reproduction.
- The capsule is a sporangium, which means it contains spores that can be dispersed for reproduction.
- The capsule consists of three parts: the apophysis, the capsule wall, and the operculum.
- The apophysis is the swollen part of the capsule that supports the capsule wall and contains the sporogenous cells.
- The capsule wall is the outer layer of the capsule that protects the spores.
- The operculum is a lid-like structure that covers the capsule and falls off to release the spores.
- The middle part of the capsule is known as the columella, which is a sterile part that does not produce spores.
- The columella is made up of sterile cells that form a central column in the capsule.
- The function of the columella is to provide support to the capsule and to help distribute nutrients to the developing sporogenous cells.
- The columella is an important part of the capsule structure, as it helps to maintain the shape of the capsule and support the development of spores.

In conclusion, the middle part of the Funaria capsule is sterile and is known as the columella. It is an important part of the capsule structure that provides support and nutrients to the developing sporogenous cells.
