Question

In Funaria, the spores are dispersed with this:

• A. Elaters
• B. Peristomial teeth
• C. Pseudoelaters
• D. Buller mechanism

Hint:

Remember that moisture plays a significant role in the dispersal mechanisms of moss spores.

Answer 1

The Correct Option is B

Step 1: Understanding spore dispersal in Funaria. 
Funaria, commonly known as moss, utilizes peristomial teeth located around the mouth of the spore capsule. These teeth are hygroscopic, meaning they respond to moisture changes. When it's dry, they bend outward to release spores, and when it's moist, they close to protect the spores inside.
Step 2: Mechanism functionality. 
The mechanism allows Funaria to efficiently disperse its spores during favorable conditions, ensuring better germination and survival rates in suitable environments.
