Hyphae that grow into host cells without killing them________

Explanation

To solve the question, we need to identify the correct term that describes "hyphae that grow into host cells without killing them." Let's go through the provided key terms step by step:

1. **Understanding the Key Terms**:
- **Chitin**: This is a component of the cell wall in fungi, but it does not relate directly to the growth into host cells.
- **Conidiophore**: This is a structure that produces conidia (asexual spores) in fungi, not related to the growth into host cells.
- **Haustoria**: These are specialized structures that some fungi develop to penetrate host cells and absorb nutrients without killing the host.
- **Hypha**: This is the basic structural unit of fungi, but it does not specifically refer to the interaction with host cells.
- **Sporangium**: This is a part of the fungus that produces and stores spores, not related to the growth into host cells.
