A retrovirus is a type of virus whose genetic material can be integrated into the host cell's DNA, making it become part of the cell's hereditary material. Examples include HIV and some types of leukemia-causing viruses.
There are unicellular organisms - that is a single cell that is an organism. However, for multicellular organisms, such as animals - a cell is only a small part of the whole organism.
By incorporating part of a host cell membrane into its envelope, a virus can disguise itself and evade detection by the host's immune system. This camouflage allows the virus to enter host cells more easily without triggering an immune response, increasing its chances of successful infection.
A latent virus remains dormant in the host cell without actively reproducing. When triggered by certain factors, such as stress or a weakened immune system, the virus can reactivate and begin replicating in the host cell to produce new viral particles.
The cell, is the smallest part of the body that is said to be alive.
A Latent Virus

The components of a virus that is injected into the infected cell is either the RNA or DNA. A virus is composed of two parts a nucleic acid part and a protein part.
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
Latent Viruses: some viruses can be latent. That means that after the virus enters a cell, its hereditary material can become part of the cell's hereditary material.

A virus is a microscopic particle that invades a cell, takes over its machinery to replicate, and ultimately destroys the cell as part of its life cycle.
A Virus
Spikes are proteins that are part of the viral capsid/envelope (depending on if the virus is a naked virus or not). It helps with attachment to the host cell. They are derived from their host cell's own proteins (but are not the same as their hosts), and can help in evading the host cell's defenses.
This is something all viruses do in effect when they attack a cell and make the cell start producing new viruses as a part of their reproductive process. See the related question below about the Lytic Cycle which describes the steps in that process.
