Gaidendron is an example of

Options

A. Total root parasite
B. Autoparasite
C. Hyperparasite
D. Partial stem parasite

Answer

**Step-by-Step Solution:**

1. **Identify the Plant Type**: The question asks about Gaidendron, which is a type of plant. To answer this, we need to understand what Gaidendron is classified as.

2. **Understand the Habitat**: Gaidendron is found mostly in temperate and tropical forests. This information helps us narrow down its characteristics and ecological role.

3. **Determine the Nature of the Plant**: Gaidendron is described as a parasitic plant. This means it relies on other plants (hosts) for its nutrition.

4. **Define Haustoria**: The plant uses structures called haustoria, which are root-like extensions that penetrate the host plant to extract water and nutrients. This is a key characteristic of parasitic plants.

5. **Classify the Type of Parasite**: Gaidendron is classified as an "autoparasite." This means it derives all its nutrients from a host plant, as opposed to other types of parasites.

6. **Eliminate Other Options**:
- A total root parasite derives all its nutrition from the roots of the host plant, which does not apply to Gaidendron.
- A hyperparasite is a parasite that feeds on another parasite, which is also not applicable here.
- A partial stem parasite obtains some nutrition but not entirely from the host, which does not fit Gaidendron's classification.

7. **Conclude the Answer**: Based on the above analysis, Gaidendron is best classified as an "autoparasite." Therefore, the correct answer is option number 2.

**Final Answer**: Gaidendron is an example of an autoparasite.
