Verified step by step guidance

Understand the definition of living organisms in the context of organic chemistry: Living organisms are typically characterized by their ability to grow, reproduce, respond to stimuli, and carry out metabolic processes independently.
Examine the structure of viruses: Viruses are composed of genetic material (either DNA or RNA) surrounded by a protein coat, and sometimes a lipid envelope. These components are organic molecules, contradicting the statement that viruses do not contain any organic molecules.
Analyze the reproduction process of viruses: Viruses cannot reproduce independently. They require a host cell to replicate, as they lack the necessary cellular machinery for independent reproduction.
Consider the metabolic capabilities of viruses: Viruses do not perform metabolic processes on their own. They rely on the host cell's metabolic machinery to carry out these processes, which is a key reason they are not considered living organisms.
Conclude why viruses are not considered living: Based on the inability to reproduce independently and lack of independent metabolic processes, viruses do not meet the criteria for living organisms in organic chemistry.
