Why scientist believe that virus are not living organisms?
viruses do not grow, and viruses do not respond to changes in their environment. Therefore, viruses are not living organisms. All living things reproduce, but Viruses need living cells to reproduce because Viruses cannot reproduce by themselves.
How are viruses harmful to living cells?
Viruses can reproduce very quickly. When reproducing they enter a living cell and they inject their genetic material.
What is a non living pathogen that invades body cells?
Viruses
What cells do the cell theory apply to?
plants and animalsmulticellular organisms fungi
Are viruses multicellular or unicellular?
Viruses are neither multicellular nor unicellular. They are not living and do not have cells. They are considered particles.
Why do you classify viruses as obligatory intracellular parasite?
Viruses need living cells to produce more viruses. They are obliged to use living cells.
Viruses depend on living things for what?
Viruses depend on living cells because they reproduce inside of them.
Is some viruses are prokaryotes and some are eukaryotes?
Viruses are neither prokaryotes nor eukaryotes as they are not living cells and do not have cell structure. They are parasites of living cells.
Where would viruses most likely grow?
Viruses can only live in living organisms (viruses themselves are not actually living). They might infect cells in our body, such as throat cells (infection of throat cells causes sore throat).
Did viruses appear before or after living cells?
no because we needed to know about living cells to know about a virus.
What types of things have cells?
Anything living. Since viruses are not living (they don't have cells) they don't count.
What are pathogens that need living cells in order to reproduce called?
Viruses need living cells for reproduction .
Why viruses are difficult to classify as living organisms?
It is because viruses are not made up of cells
Why scientist believe that virus are not living organisms?

What is a non living pathogen that invades body cells?
Viruses
What is the only characteristics shared by living cells and viruses?
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Living cells also contain DNA and RNA. These are the only thing shared by living cells and viruses.
