Identify the incorrect match.

Options

A. Chlamydomonas - Zoospore
B. Penicillium - Conidia
C. Hydra - Gemmules
D. Amoeba - Binary fission

Answer

To identify the incorrect match from the given options, we need to analyze each option provided in the question:

1. **Chlamydomonas and Zoospores**:
- Chlamydomonas is a unicellular green alga that reproduces asexually through motile spores known as zoospores. This match is correct.

2. **Penicillium and Conidia**:
- Penicillium is a genus of fungi that reproduces asexually through structures called conidia, which are non-motile spores. This match is also correct.

3. **Hydra and Grammules**:
- Hydra is a freshwater cnidarian that primarily reproduces asexually through budding. The term "grammules" is incorrectly associated with Hydra; grammules are actually asexual reproductive structures found in freshwater sponges. Therefore, this match is incorrect.

4. **Amoeba and Binary Fission**:
- Amoeba reproduces asexually through binary fission, where one amoeba divides into two. This match is correct.

Based on the analysis, the incorrect match is **Hydra and Grammules**.

### Step-by-Step Solution:
1. **Identify the organisms and their reproductive structures**:
- Chlamydomonas - Zoospores
- Penicillium - Conidia
- Hydra - Grammules
- Amoeba - Binary Fission

2. **Evaluate the correctness of each match**:
- Chlamydomonas does produce zoospores, which is correct.
- Penicillium does produce conidia, which is correct.
- Hydra does not produce grammules; it reproduces by budding, making this match incorrect.
- Amoeba does reproduce by binary fission, which is correct.

3. **Conclude the incorrect match**:
- The incorrect match is Hydra with Grammules.
