Plasma membrane is presentA virus can easily manipulate various cellular activities once it has already invadedthe host cell. Does this mean that a virus is a living organism because it can enter acell, the fundamental unit of life? Provide a brief explanation as to its relationship with the principle of cell theoryinvolved. Thank youOne way to understand cell function is to compare the parts of a cellto the parts of a factory. For example, the Golgi apparatus would beanalogous to the factory’s shipping department. How would the othercell parts fit into this analogy?
