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.

Answer

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

1. **Cyanobacteria are called blue-green algae.**
- This statement is **correct**. Cyanobacteria, often referred to as blue-green algae, are photosynthetic bacteria that contain chlorophyll and other pigments, giving them their characteristic color.

2. **Golden algae are also called the test mates.**
- This statement is also **correct**. Golden algae, which belong to the group Chrysophyta, are indeed referred to as test mates due to their siliceous shells or tests.

3. **Eubacteria is also called the false bacteria.**
- This statement is **wrong**. Eubacteria are commonly known as true bacteria, not false bacteria. The term "false bacteria" is not used to describe Eubacteria.

4. **Phycomycetes is also called the Algal Fungi.**
- This statement is **correct**. Phycomycetes, a group of fungi, are often referred to as algal fungi due to their similarities with algae.

Based on the evaluation, the wrong statement is: **Eubacteria is also called the false bacteria.**
