What is a virus ?
Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
The cell membrane is made up of a phospholipids that are arranged into two layers which are called lipid bilayer.
They are not from the periodic elements scientifically.
Cell walls, which are found in plant cells, maintain cell shape. Some animal cells dont need to maintain shape. Such as muscle cells, they are constantly moving.
