How are viruses which typically have a lipid covering called an envelope released from the host cell?
Viruses with an envelope are released from host cells by budding off the cell membrane. During this process, the virus pushes through the host cell's membrane, acquiring an envelope derived from the host cell's membrane. This budding process allows the virus to leave the host cell without causing immediate cell death.
What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
Could cell survive without a cell membranes?
At this time, there is no evidence that prokaryote or eukaryote cells can survive without a cell membrane and be metabolically active at the same time.Many viruses don't have cell membrane but a a protein core instead. Viruses cannot be considered as living cell but infective particles because they are not active outside host cells.
Are viruses surrounded by a cell wall?
No, but all cells have a cell membrane. A cell wall is a rigid structure found surrounding the cell membrane. In plant cells, this is made of cellulose, hemicellulose and pectin. Bacteria have a peptidoglycan cell wall. Animal cells do not have a cell wall.
Cell membrane and protein coat same thing?
No, the cell membrane and protein coat are not the same thing. The cell membrane is a phospholipid bilayer that surrounds the cell, providing structure and regulating what goes in and out. A protein coat, on the other hand, is a protective layer made of proteins that surrounds some viruses.
Is there a cell membrane in viruses?
Viruses dont have a cell membrane. Instead, they have a protein sheath.
Do viruses have a nuclear membrane a cell wall membrane-bound organelles or ribosomes?
No, viruses do not have membrane bound organalles
What attracts viruses?
receptors on cell membrane
What doesn't the viruses have?
the viruses doesn't have is no nucleus, cytoplasm,organelles, or cell membrane.
How does the cell membrane help the plant cell?
The Cell Membrane helps the plant cell by guarding any viruses that come near it.
Do Most DNA viruses multiply in the host cell's cell membrane?
No, DNA viruses multiply in the host cell's nucleus, while most RNA viruses multiply in the host cell's cytoplasm
Why are viruses so specific in the cell the infect?
Viruses have specific proteins on them which only binds to certain receptors, which are present in certain cell's plasma membrane.

Viruses cannot be considered as living cell but infective particles because they are not active outside host cells.
Does a virus contain a cell membrane?
No, viruses do not contain a cell membrane. Viruses are simple infectious agents composed of genetic material (DNA or RNA) surrounded by a protein coat called a capsid. They lack the complex cellular structures found in living cells.
