4. | None of the members is unicellular. |
Identify the incorrect statement regarding body organization in fungi:
1. | With the exception of yeast, fungi are filamentous. |
2. | Their bodies consist of long, slender hyphae that may be coenocytic or septate. |
3. | The network of hyphae is known as the mycelium. |
4. | The cell walls of fungi lack chitin and polysachharides. |
I: | Their bodies consist of long, slender thread-like structures called hyphae. |
II: | The network of hyphae is known as mycelium. |
III: | Some hyphae are continuous tubes filled with multinucleated cytoplasm – these are called coenocytic hyphae. |
IV: | The cell walls of fungi are composed of chitin and polysaccharides. |
