cell membranes are in all types of cells.
They control what materials go in and out of the cell which is very important because without it, many harmful products would go into the cell.
Virus have no cells
The virus attaches to the host cells membrane.
the virus attaches to the host cells membrane
When a virus breaks through a cell wall/ membrane and infects the cytoplasm.
This membrane envelope is taken from the last victim of the virus as it exits the cell and contains general identification proteins and docking proteins that the virus can use to gain entry to another cell. The AIDS virus use a docking analogue to dock in the CD4 protein docking area of a T-cell, this facilitates it's entry into the T-cell.
A cytotoxic T cell kills cells that have been infected by a virus or bacterium. It does this by puncturing the cell's membrane and by emitting a toxin that kills cells.
All cells have a cell membrane! Only "plant cells" have a cell wall, and a cell membrane!
There are no cells in a cell membrane.,
The process by which a cell membrane absorbs a virus is called endocytosis. Specifically, a type known as viral endocytosis occurs when the cell membrane engulfs the virus, allowing it to enter the cell. This mechanism enables viruses to penetrate host cells and initiate infection. Once inside, the virus can then release its genetic material and hijack the host's cellular machinery for replication.
The cytotoxic T cell, when it finds cells displaying the wrong antigens, ruptures the cell membrane of the offending cell killing it. Cytotoxic T cells are effective against virus infected cells and cancer cells.

There is a cell membrane in plant cells and in animal cells.
