Why does the structure of plant and bacterial cells illustrate the reason for having few enveloped viruses that infect these cells?

Presence of cell wall around plant and bacteria cells do not allow the budding of enveloped viruses.

Explanation:

During infection, replication of genome and formation of capsid proteins of enveloped viruses within the host cell is followed by assembly of capsid around each viral genome molecule which in turn bud off from the membrane of the host cell. As the new virus buds off from the cell surface, it acquires envelop from the host cell.

The presence of cellulosic and peptidoglycan cell walls around plant and bacteria cells respectively does not allow the budding of the enveloped viral particles. Consequently, these viruses can not acquire the envelope and hence, do not affect these cells with cell walls.

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.
