Use the given key terms in the box to fill in the puzzle. You will not use all the terms.
chitin conidiophore haustoria
hypha sporangium mycelium
Basic structural unit of fungi_________

Explanation

To solve the puzzle, we need to identify the basic structural unit of fungi from the given key terms. Here’s the step-by-step solution:

1. **Understanding the Terms**: We have several key terms related to fungi: chitin, conidiophore, haustoria, hypha, sporangium, and mycelium. We need to determine which of these terms represents the basic structural unit of fungi.

2. **Analyzing Each Term**:
- **Chitin**: This is a component of the cell wall in fungi but not a structural unit itself.
- **Conidiophore**: This is a specialized structure that produces conidia (asexual spores) but is not the basic unit.
- **Haustoria**: These are specialized structures for nutrient absorption but are not the basic unit.
