Answer:
Virus enters into the host cell through a process called endocytosis.
Explanation:
Endocytosis is a process in which molecule enters into the cell through cell membrane. Virus also enter into the host cell through this process. After entering, the virus starts replication and grow in numbers inside the host cell and take nutrients from it which is used in the process of reproduction. When virus population increases, it cause infection to the neighboring cells.
Meiosis is the process of making sex cells(haploid cells). This is the main component of reproduction. Therfore, the greatest benefit is reproduction.
