A plant living symbiotically inside another plant is

Options

A. Saprophyte
B. Endophyte
C. Semiparasite
D. Parasite.

Answer

To answer the question "A plant living symbiotically inside another plant is," we will analyze the options provided and identify the correct term that describes this relationship.

### Step-by-Step Solution:

1. **Understanding the Options**:
- The question presents four options: saprophyte, endophyte, semi-parasite, and parasite. We need to determine which of these describes a plant that lives symbiotically inside another plant.

2. **Analyzing the First Option - Saprophyte**:
- A saprophyte is a type of organism that feeds on dead organic matter. Since the question specifies a plant living symbiotically inside another plant, this option does not fit.
- **Conclusion**: Saprophyte is incorrect.

3. **Analyzing the Second Option - Endophyte**:
- The term "endophyte" refers to organisms (often fungi or bacteria) that live inside a plant without causing harm. This relationship can be mutually beneficial, as the endophyte can help the host plant by providing nutrients or enhancing resistance to stress.
- **Conclusion**: Endophyte is the correct answer.

4. **Analyzing the Third Option - Semi-parasite**:
- Semi-parasites are organisms that can produce their own food through photosynthesis but depend on other plants for water and nutrients. While they do have a relationship with other plants, it is not symbiotic in the same way that endophytes are.
- **Conclusion**: Semi-parasite is incorrect.

5. **Analyzing the Fourth Option - Parasite**:
- Parasites are organisms that live on or in a host and derive nutrients at the host's expense, often harming it in the process. This does not align with the definition of a symbiotic relationship, where both organisms benefit.
- **Conclusion**: Parasite is incorrect.

### Final Answer:
The correct answer is **endophyte**.
