Which one of the following is correctly matched?

Options

A. Onion-Bulb
B. Ginger-Sucker
C. Chlamydomonas-Conidia
D. Yeast-Zoospores

Answer

To determine which option is correctly matched, we will analyze each option provided in the question:

1. **Onion - Bulb**
- An onion is a type of bulb, which is a specialized underground bud of monocotyledonous plants. Bulbs consist of a short fleshy storage stem surrounded by thick scales (modified leaves). Therefore, this option is correctly matched.

2. **Ginger - Sucker**
- Ginger is not a sucker; it is classified as a rhizome. A rhizome is a modified stem that grows horizontally underground and can produce shoots and roots from its nodes. Thus, this option is incorrectly matched.

3. **Chlamydomonas - Conidia**
- Chlamydomonas is a unicellular green alga that reproduces asexually by producing zoospores, not conidia. Conidia are a type of asexual spore produced by certain fungi. Therefore, this option is incorrectly matched.

4. **Yeast - Zoospores**
- Yeast is a unicellular fungus that reproduces asexually primarily through budding, not by zoospores. Zoospores are flagellated spores found in some algae and fungi, but not in yeast. Hence, this option is also incorrectly matched.

After analyzing all options, we conclude that the only correctly matched option is:

**Correct Answer: Onion - Bulb**
