Answer
The absence of an envelope makes viruses more resistant to certain environmental conditions and disinfectants, and changes their mode of entry into host cells.
Solution
a
Resistance to environmental conditions: Non-enveloped viruses are generally more resistant to drying, heat, detergents, and other harsh environmental conditions compared to enveloped viruses
b
Disinfectants: Enveloped viruses are more susceptible to disinfectants because the envelope can be disrupted easily, whereas non-enveloped viruses are more resistant to disinfectants
c
Mode of entry: Non-enveloped viruses often rely on more robust mechanisms to penetrate the host cell, such as endocytosis or direct penetration of the cell membrane, since they lack the lipid envelope that facilitates fusion with the host cell membrane
Key Concept
Envelope absence in viruses
Explanation
The absence of an envelope in viruses confers increased resistance to environmental stressors and affects their interaction with host cells.
