Current Question (ID: 11896)

Question:

$\text{Which one of the following statements is wrong?}$

Options:

1. $\text{Golden algae are also called desmids}$
2. $\text{Eubacteria are also called false bacteria}$ (Correct)
3. $\text{Phycomycetes are also called algal fungi}$
4. $\text{Cyanobacteria are also called blue-green algae}$

Solution:

$\text{Explanation:}$ $\text{Eubacteria are true bacteria which exhibit all true characteristic features of group Eubacteria.}$ $\text{The statement that 'Eubacteria are also called false bacteria' is incorrect because:}$ $\text{- Golden algae (Chrysophyceae) include desmids as a group, so statement 1 is correct}$ $\text{- Phycomycetes are indeed called algal fungi due to their algae-like characteristics, so statement 3 is correct}$ $\text{- Cyanobacteria are commonly known as blue-green algae, so statement 4 is correct}$ $\text{- Eubacteria are TRUE bacteria, not false bacteria, making statement 2 wrong}$
