Virus are non-cellular organisms. They are small particles, smaller than bacteria. They infect every type of living organism. As well as they have wide variety of shapes and sizes. ✌️
Structures Of Virus:
They have no cellular structure, it consists of protein coat which encloses the nucleic acid (DNA or RNA). They have a protein coat which is covered by an envelope that are made of lipid and protein with glycolipid and glycoprotein attached to it. 😁
Reproduction of Virus:
Since they cannot reproduce by themselves and as they are parasitic they reproduce inside a host cell. The virus takes over the enzymes machinery of the host cell to produce new virus particles.💯
