Which one of the following pairs is wrongly matched

Options

A. Ginkgo-Archegonia
B. Salvinia-Prothallus
C. Viroids-RNA
D. Mustard-Synergids

Answer

To determine which pair is wrongly matched, we will analyze each pair mentioned in the transcript step by step.

### Step 1: Analyze the first pair - Ginkgo and Archi-Gonyo
- Ginkgo is a type of gymnosperm.
- Archi-Gonyo is a female gamete-producing organ, primarily found in plants like Marchantia (a liverwort) and mosses.
- Since Ginkgo also has a female reproductive structure, this pair is correctly matched.

**Hint:** Check if both terms in the pair belong to the same category of plant structures or types.

### Step 2: Analyze the second pair - Selvenia and Prothelus
- Prothelus is a gametophytic stage found in ferns (pteridophytes).
- In Selvenia, the gametophyte is heterosporous, meaning it produces different types of spores for male and female gametes.
- Prothelus is not present in Selvenia as it does not form a single structure with both male and female organs; instead, they are separate.
- Therefore, this pair is wrongly matched.

**Hint:** Consider whether the reproductive structures or stages mentioned in the pair are compatible with each other.

### Step 3: Analyze the third pair - Viroids
- Viroids are indeed the smallest infectious agents, consisting of single-stranded RNA without a protein coat.
- This description is accurate, and thus this pair is correctly matched.

**Hint:** Verify if the definitions or characteristics of the terms align with established scientific knowledge.

### Step 4: Analyze the fourth pair - Mustard and Synergies
- Mustard is an angiosperm.
- Synergies are the cells surrounding the egg in the female gametophyte (embryo sac) and are involved in guiding the pollen tube.
- Since synergies are present in mustard, this pair is correctly matched.

**Hint:** Check if the reproductive structures mentioned are found in the specified plant type.

### Conclusion
After analyzing all the pairs, the wrongly matched pair is **Selvenia and Prothelus**.

**Final Answer:** The wrongly matched pair is Selvenia and Prothelus.
