All living things possess certain characteristics, including the ability to grow, reproduce, respond to stimuli, maintain homeostasis, and obtain and use energy.
Viruses react to the environment, reproduce (through asexual means), and need energy to survive. They are also capable of passing hereditary information, but that could be included in reproduction.
Viruses do not behave like other living cells. For one, they can only reproduce within other organisms. And essentially that is about all they do. Granted there are negative reprocussions for the host organism, but the virus itself simply multiplies. Viruses are also smaller than cells and can use even simple bacteria as a host. They are considered to be more like "free floating chemical agents."
Living organisms possess several characteristics that distinguish them from non-living entities. These include the ability to grow, reproduce, respond to stimuli, maintain homeostasis, and adapt to their environment. Additionally, living organisms require energy to carry out these functions and are made up of cells, which are the basic units of life.
Pretty much everything.Since viruses are not alive, they have many things in common with that of a non-living things. Some of these characteristics includes:cannot reproduce (viruses need a host in order to reproduce)cannot adapt to the environment (although they change, this is not an environmental adaption)are not made of a cell, nor are they composed of cells. (viruses are much smaller than that of a cell)cannot metabolize (viruses do not eat for energy, nor do they excrete waste material. They only use the energy made by the host cell, or the kinetic energy in gravity, wind, etc.)cannot grow (viruses can only be "assembled" when infecting the host cell.)
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.
Viruses have some characteristics of life but these are not considered living organisms as they are non cellular.
Viruses are not classified in a kingdom because they do not possess all the characteristics of living organisms. They lack cellular structure, cannot carry out metabolic processes on their own, and cannot reproduce without a host cell. As a result, they are often considered biological entities that straddle the line between living and non-living.

Viruses have some, but not all, of the characteristics of living things.
viruses do not have the ability to replicate on their own or carry out metabolic functions like living organisms do. They require a host cell to reproduce and do not possess the machinery needed to do so independently.
Viruses are considered non-living because they cannot carry out cellular activities on their own. They require a host cell to replicate and do not possess the ability to metabolize or grow.
Yes **G1N4** I thought some living things are not organisms, because they are not free living.
Viruses lack cellular structure and cannot replicate on their own. They rely on infecting host cells to reproduce, making them dependent on other living organisms for their survival. Additionally, viruses do not possess the machinery necessary for metabolism and energy production, key characteristics of living organisms.
No, gold is a mineral and an inanimate substance. It does not possess the characteristics of living organisms such as growth, reproduction, or metabolism.
They reproduce.
