Choose the incorrect statement about members of the kingdom Fungi.

Options

A. With the exception of yeasts which are unicellular , fungi are filamentous .
B. The fungal cell walls is made of cellulose and pectin.
C. Fungal bodies consist of long , slender thread - like structures called hyphae.
D. Some hyphae are continuous tubes filled with multinucleated cytoplasm known as coenocytic hyphae.

Answer

To solve the question about the incorrect statement regarding members of the kingdom Fungi, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- The first statement claims that "with the exception of yeast, which are unicellular, fungi are filamentous."
- This statement is correct because most fungi are indeed multicellular and filamentous, forming structures called hyphae. Yeasts are the exception as they are unicellular.

**Hint:** Remember that yeasts are unicellular fungi, while most fungi are multicellular and filamentous.

2. **Analyze the Second Statement:**
- The second statement claims that "the fungal cell wall is made up of cellulose and pectin."
- This statement is incorrect. Fungal cell walls are primarily composed of chitin, not cellulose and pectin, which are found in plant cell walls.

**Hint:** Recall that chitin is the main component of fungal cell walls, distinguishing them from plant cell walls.

3. **Analyze the Third Statement:**
- The third statement states that "fungal bodies consist of long cylindrical structures called hyphae."
- This statement is correct as hyphae are indeed the thread-like structures that make up the body of most fungi.

**Hint:** Hyphae are the fundamental units of fungal structure.

4. **Analyze the Fourth Statement:**
- The fourth statement mentions that "some hyphae are continuous tubes filled with multinucleated cytoplasm known as cenocytic hyphae."
- This statement is also correct. Cenocytic (or coenocytic) hyphae lack septa and contain multiple nuclei within a single cell.

**Hint:** Cenocytic hyphae are characterized by the absence of septa, allowing for a multinucleated condition.

### Conclusion:
After analyzing all statements, the incorrect statement about members of the kingdom Fungi is the second one: "the fungal cell wall is made up of cellulose and pectin."

### Final Answer:
The incorrect statement is: **"Fungal cell wall is made up of cellulose and pectin."**
