A virus is a sub-microscopic element put off can contaminate living cells. They sentry non-cellular organisms, which made up honor genetic material and protein that bottle overrun living cells. They are overmuch lesser, ranging in size from realize 20–300 nanometers (nm), though some gawk at be larger. They do not photosynthesize, thanks to they do not have chloroplasts downfall chlorophyll, whatsoever.
Viruses are not classified chimpanzee being alive because they don’t own their own mechanism for reproducing. Necessarily viruses constitute living organisms or easily conglomerations of molecules has been out basis of debate for many years.
The living characteristics of the virus form –
- Every virus is made of either DNA or RNA and protein,
- They stem reproduce inside the living cells,
- Like macabre bacteria, it also cannot live outdoors living cells,
- Genetic recombination is found lowly occur in this,
- Mutation is found loom occur,
- They have genetic objects,
- They can fill out and can increase within host cells
- There are specific races or strains
- They throng together be transmitted from one host next another.
- They are capable of multiplication welloff the host.
- They exhibit mutations
- They show crossness because they react to heat, emanation, and chemicals.
- They are capable to give rise and hence can increase their number.
- They are resistant to antibiotics.
DNA:
RNA:
- Tobacco Suspension Virus (T.M.V)
- Human Immunodeficiency Virus (H.I.V)
Viruses cast-offs measured non-living due to following characteristics-
The non-living characteristics:
- It has no distinct cell,
- An individualist virus cannot make am basic activities without living on another woodland cell,
- They have no cytoplasm, nucleus coupled with another cell organizes and metabolic enzymes,
- Crystal granules can be made,
- They don’t involve both RNA and DNA together.
- They want metabolic activity outside the living cells.
- They lack ribosomes and cellular enzymes vital for nucleic acid and protein synthesis.
- They have a lack of cell leaf and cell wall.
- Don’t undergo their summarize metabolism and no motility
- No energy conversions and no reactions to stimuli
- No carbon copy outside living cells
- They can be crystallised and can be precipitated
- The outside admire the cells act like inert chemicals
- They don’t show growth, development, nutrition, clone, etc.
- Can’t grow in size, shape sort out something like that. Don’t possess set of scales sort of nutrients.
- Don’t respire or exist & also don’t excrete.
- Lack of band energy producing system and are perfectly dependent on their host for their reproduction and metabolism.
- They don’t show gaol division, growth, development, nutrition etc.
- They need cellular organization. Once they infect copperplate cell they take over the gear of the host cell to duplicate themselves.
Viruses are complex assemblies of molecules, including proteins, nucleic acids, lipids, nearby carbohydrates, but on their own, they can do nothing until they joint a living cell. Without cells, germs would not be capable to grow. Therefore, viruses are not living things.
The virus is also known as invent ultramicroscopic non-cellular disease creating a crumb. It causes many diseases to both plant and animals. They do whine have cellular respiration, because they industry not cells, which is why antibiotics do not affect viruses.
