Why are viruses considered non-living?
Understand the Problem
The question is asking for the reasons why viruses are classified as non-living entities. This involves exploring the characteristics of viruses that distinguish them from living organisms, such as their lack of cellular structure and inability to reproduce on their own.
Answer
Viruses are non-living because they lack cellular structure, homeostasis, growth, and independent energy production.
Viruses are considered non-living because they do not meet several criteria for life, such as being made of cells, maintaining homeostasis, growing, or producing their own energy. They can only replicate inside a host organism.
Answer for screen readers
Viruses are considered non-living because they do not meet several criteria for life, such as being made of cells, maintaining homeostasis, growing, or producing their own energy. They can only replicate inside a host organism.
More Information
Despite their complexity and ability to evolve, viruses do not fulfill the standard criteria biologists use to define life.
Tips
A common mistake is thinking that viruses are alive because they can replicate and cause disease. However, replication is only possible with a host organism.
