The cell wall is a sturdy layer that offers protection and structural support to cells. Its composition differs across organisms, such as chitin, glucans, and glycoproteins in some, while cellulose and hemicellulose are found in land plants. Peptidoglycan makes up the cell walls of Archaea. Which of the following statements is accurate?

1. Eubacteria are considered true bacteria.
2. Alternaria is a member of Deuteromycetes, a class lacking sexual reproduction, with asexual reproduction occurring via conidia formed on conidiophores.
3. Anabaena, a cyanobacterium, lacks a true nucleus due to the absence of a nuclear membrane.
4. The Deuteromycetes class, also known as imperfect fungi, contributes to the breakdown of organic matter.

Correct answer: Anabaena, a cyanobacterium, lacks a true nucleus due to the absence of a nuclear membrane.

Solution

Anabaena is a cyanobacterium, which is a prokaryote. Prokaryotes lack a true nucleus as they do not have a nuclear membrane, making option C correct.
