Meristems are devoid of _ due to the absence of vascular system in them.
Correct answer: D. Virus
- A. Bacteria
- B. Algae
- C. Fungus
- D. Virus
Explanation
Meristems are devoid of viruses because they lack a vascular system. Since viruses require a host to replicate and spread, the absence of a vascular system in meristems prevents them from being infected by viruses. This helps keep the meristems healthy and free from viral infections.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
