Which one of the following statements is wrong?

Options

A. Cyanobacteria are also called blue-green algae
B. Golden algae are also called desmids
C. Eubacteria are also called false bacteria
D. Phycomycetes are also called algal fungi

Explanation

To determine which statement is wrong, we will analyze each option provided in the question step by step.

### Step 1: Analyze the first statement
**Statement:** Cyanobacteria are also called blue-green algae.
**Analysis:** This statement is correct. Cyanobacteria are indeed referred to as blue-green algae due to their blue and green pigments, specifically phycocyanin (blue) and chlorophyll (green), which allow them to perform photosynthesis.

### Step 2: Analyze the second statement
**Statement:** Golden algae are also called diatoms.
**Analysis:** This statement is incorrect. Golden algae are not called diatoms; they are known for their golden-brown color due to the pigment fucoxanthin. Diatoms are a different group of algae characterized by their silica cell walls. Therefore, this statement is wrong.

### Step 3: Analyze the third statement
**Statement:** Eubacteria are also called false bacteria.
**Analysis:** This statement is incorrect. Eubacteria are referred to as true bacteria, not false bacteria. They belong to the kingdom Monera and are characterized as prokaryotes with a cell wall made of peptidoglycan. Therefore, this statement is wrong.

### Step 4: Analyze the fourth statement
**Statement:** Phycomycetes are also called algal fungi.
**Analysis:** This statement is correct. Phycomycetes are a group of fungi that exhibit algae-like characteristics, such as a thallus-like structure and aquatic habitats. Thus, this statement is true.

### Conclusion
After analyzing all the statements, we find that the wrong statements are:
1. Eubacteria are also called false bacteria.
2. Golden algae are also called diatoms.

However, since the question asks for one wrong statement, the most commonly recognized incorrect statement is that Eubacteria are called false bacteria.

### Final Answer
The wrong statement is: **Eubacteria are also called false bacteria.**
