Which of the following is a parasite?

Options

A. Venus flytrap
B. Pitcher plant
C. Sundew
D. Dodder

Answer

To determine which of the given options is a parasite, we need to analyze each option based on their characteristics.

### Step-by-Step Solution:

1. **Understanding the Definition of a Parasite**:
- A parasite is an organism that lives on or in a host organism and gets its food at the expense of its host. Parasites typically do not have chlorophyll and cannot perform photosynthesis.

2. **Evaluating the Options**:
- **Venus Flytrap**: This is a carnivorous plant that traps and digests insects for nutrients. It is not a parasite because it can perform photosynthesis and does not rely on another plant for sustenance.
- **Pitcher Plant**: Similar to the Venus Flytrap, the pitcher plant is also a carnivorous plant that captures insects using its pitcher-shaped leaves. It is not a parasite as it can produce its own food through photosynthesis.
- **Sundew**: Sundew plants are another type of carnivorous plant that uses sticky hairs on their leaves to trap insects. Like the previous two, sundews can photosynthesize and are not parasites.
- **Dodder (Cuscuta)**: This is a true parasitic plant. Dodder lacks chlorophyll and cannot photosynthesize. It wraps around host plants and extracts nutrients from them, weakening the host in the process.

3. **Conclusion**:
- Based on the analysis, the correct answer to the question "Which of the following is a parasite?" is **Dodder**.

### Final Answer:
The correct option is **Dodder**.
