The correct Answer is:
To answer the question "Funaria is fixed to substratum by," we will analyze the options provided and determine the correct one based on the characteristics of Funaria. ### Step-by-Step Solution: 1. **Understanding Funaria**: Funaria is a type of moss, and its vegetative body is primarily represented by leafy structures known as gametophores. 2. **Role of Rhizoids**: These gametophores are anchored to the substratum (the surface they grow on) by structures called rhizoids. Rhizoids serve as anchoring structures that help the plant remain fixed in place. 3. **Characteristics of Rhizoids**: - The rhizoids of Funaria are described as being **branched**, **slender**, and **multicellular**. - They are not unicellular, which eliminates the first option. - They are also not tuberculate or xenocytic, which eliminates the last two options. 4. **Identifying the Correct Option**: - The second option states that they are **multicellular branched oblique septate rhizoids**. This description matches the characteristics of Funaria's rhizoids as they are indeed multicellular and branched. - Therefore, the correct answer is **option 2: multicellular branched oblique septate rhizoids**. ### Final Answer: Funaria is fixed to the substratum by **multicellular branched oblique septate rhizoids**.
