Plants capable of growing in nitrogen deficient soil is

Options

A. Orchids
B. Ferns
C. Insectivorous plants
D. Raffesia

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for plants that can thrive in nitrogen-deficient soil. This implies that these plants have adapted mechanisms to obtain nitrogen from sources other than the soil.

2. **Analyzing the Options**:
- **Orchids**: Typically, orchids are epiphytes and rely on nutrients from the environment, but they still require nitrogen from the soil.
- **Ferns**: Ferns also absorb nitrogen from the soil through their roots and are not specialized for nitrogen-deficient conditions.
- **Insectivorous Plants**: These plants, such as Venus flytraps and pitcher plants, have adapted to obtain nitrogen by digesting insects. This allows them to thrive in nitrogen-poor environments.
- **Raphesia**: This is a genus of flowering plants that also relies on soil nutrients, including nitrogen.

3. **Identifying the Correct Answer**: Among the options, insectivorous plants are the only ones that can grow in nitrogen-deficient soil because they supplement their nitrogen intake by consuming insects.

4. **Conclusion**: The correct answer to the question is **insectivorous plants**.
