life activities
No, viruses do not meet all the criteria of the cell theory because they are acellular entities that cannot carry out cellular functions on their own. Viruses require a host cell to replicate and carry out their life cycle.
The smallest unit that can carry on all activities of life in a cell is the cell itself. Cells are the basic structural and functional unit of all living organisms. Each cell is capable of performing essential functions such as metabolism, growth, and reproduction.
A cell. Cells are the basic unit of life. Unicellular organisms can perform life tasks on its own, and they are one cell. Multicellular organisims have more than one cell (you and I), and can also perform life tasks.
Fermentation.
The smallest unit that can carry on all the processes of life is a cell. The cell membrane is made of phospholipids.
A virus is a particle that can carry out some life processes, such as reproduction and evolution, but requires a host cell to carry out metabolic processes. Viruses are considered obligate intracellular parasites and cannot replicate on their own.
All living things are organisms. There is no such thing as a living cell that is not an organism.

The cell
No, viruses cannot carry out all life processes on their own as they lack cellular machinery for functions like metabolism and reproduction. Viruses require a host cell to replicate and express their genetic material.
