Many, if not most biologists do not consider viruses living. So, they are not on any phylogenetic tree that I know of. They may have a phylogeny that I am unaware of, though.
Right at It's Roots.
The type of cells that viruses live in are host cells. Viruses need host cells in order to reproduce or multiply.
Viruses do not have all the characteristics of life. They are missing life span, homeostasis, metabolism, growth and are not made of cells.
Viruses are considered non-living because they do not use 6 of the seven life proceses
The only life function that a virus shares with a cell is reproduction. Both cells and viruses reproduce in some way.
Right at It's Roots.
None. Viruses are acellular. Many biologists do not consider viruses to be living things in part because they are acellular. Look at any phylogeny (tree of life). Viruses are not on them.
Since viruses are not alive they can not have life processes.
The type of cells that viruses live in are host cells. Viruses need host cells in order to reproduce or multiply.
There are no known viruses that can be hosted by a tree. There are however parisites and Fungi that can be harmfull to any plant, shrub, or tree. The only example I know of where a tree might harbor a viruse is if a bark beetle was to by chance have the flu.
It is not called The tree of Life.
Neither, viruses are unique to themselves and don't belong to any classification of life. Viruses are not considered living things because they do not perform all the functions of life therefore they are considered organic particles.
Not at all.The tree of life is totally different.
Viruses do not have all the characteristics of life. They are missing life span, homeostasis, metabolism, growth and are not made of cells.
Neither - viruses do not eat. There are debates about whether viruses are a form of life, or organic structures that interact with living organisms.
No
Viruses have the ability to greatly affect life on earth. Many viruses, such as HIV and influenza have killed millions of people. By studying viruses, scientists are able to develop vaccines that will protect people (and animals) from viruses.
