Nucleic acid
DNA or RNA
Active (non-killed) viruses are living organisms.
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
It is because viruses are not made up of cells
They are living, but they are not organisms. Cells are the "building blocks" of tissues, which group together into organs, which group together into organ systems. Those organ systems comprise an organism. The individuals cells are not organisms themselves.
Viruses are not classified as living, while cellular organisms are. Viruses are essentially a protein case with mRNA inside. Cells are far more complicated.
The smallest complete living unit known to science is a single cell. The smallest single celled organisms known, mycoplasma, are not much bigger than the very largest viruses. Viruses are not technically considered to be living organisms by most scientists.
Living organisms have a cell membrane containing cytoplasm. Some viruses are the exception, being made of proteins, but many types of viruses are surrounded by a lipid membrane.
single celled organisms
Multi because they are living and breathing. Something like a rock would be single celled.
viruses are non living and bacteria are living organisms
Yes.
Single-celled Organisms was written by Helmut Schenk.
Bacteria and viruses are small and can only be seen through a microscope. The small living things are microorganisms or microbes. Some people do not think viruses are living things because they are acellular particles. They consider them to be an organic structure that interacts with 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.
Active (non-killed) viruses are living organisms.
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
Bacteria are microscopic, single-celled organisms. Living bacteria are not dead.
