Which of the following pairs is not correctly matched

Options

A. Rhizome: Banana
B. Binary fission: Sargassum
C. Conidia: Penicillium
D. Offset: Water hyacinth

Answer

To determine which of the following pairs is not correctly matched, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Option 1: Rhizome and Banana**
- **Analysis:** The banana plant reproduces asexually through a structure called a rhizome, which is a modified underground stem. The rhizome contains buds that can sprout and form new plants, known as suckers.
- **Conclusion:** This pair is correctly matched.

2. **Option 2: Binary Fission and Sargassum**
- **Analysis:** Binary fission is a method of asexual reproduction where a single organism divides into two equal parts. This method is commonly seen in unicellular organisms like amoeba. Sargassum, on the other hand, reproduces primarily through vegetative methods or the formation of sex organs, not binary fission.
- **Conclusion:** This pair is not correctly matched.

3. **Option 3: Conidia and Penicillium**
- **Analysis:** Conidia are asexual spores produced by fungi, including Penicillium. These spores are formed on specialized structures called conidiophores and are involved in asexual reproduction.
- **Conclusion:** This pair is correctly matched.

4. **Option 4: Offset and Water Hyacinth**
- **Analysis:** Water hyacinth reproduces vegetatively through offsets, which are horizontal stems that grow above the water surface and produce new plants. This method allows for rapid spread in aquatic environments.
- **Conclusion:** This pair is correctly matched.

### Final Answer:
The pair that is not correctly matched is **Binary Fission and Sargassum**.
