Aquatic weed Salvinia, also called the sorrow of Kashmir, is

Options

A. Heterosporous water fern
B. Homosporous water fern
C. Memberof bryophyte
D. Both (1) and (3)

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to Salvinia, an aquatic weed commonly known as the "sorrow of Kashmir."

2. **Classification**: Salvinia belongs to the group of plants known as Pteridophytes, which are vascular plants that reproduce via spores.

3. **Differentiate Between Types of Spores**:
- **Heterosporous**: This means that the plant produces two different types of spores—microspores (male) and megaspores (female).
- **Homosporous**: This means that the plant produces only one type of spore that is typically the same size and type.

4. **Determine the Type of Spores in Salvinia**: Salvinia is classified as heterosporous, meaning it produces two types of spores. This is significant as it allows for a more complex reproductive strategy.

5. **Eliminate Incorrect Options**:
- Since Salvinia is not a bryophyte (which includes mosses and liverworts), we can eliminate any options that suggest it belongs to that group.
- Confirm that Salvinia is indeed a member of the Pteridophytes and specifically a water fern.

6. **Conclusion**: Based on the classification and characteristics of Salvinia, the correct answer to the question is that Salvinia is a heterosporous water fern.

**Final Answer**: Salvinia, also known as the sorrow of Kashmir, is a heterosporous water fern belonging to the group of Pteridophytes.
