Generally viruses are smaller than bacteria, which are themselves smaller than animal and plant cells. Therefore D is the smallest and is least likely to be visible using an ordinary microscope.
See related links for an interactive scale of cells, from the macroscopic to the microscopic, down to a single carbon atom.

What isn't in the animal kingdom?
plants, fungi, bacteria, unicellular organisms
What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
What can you see through the light microscope?
Plant cells, animal cells and bacteria can be visualized through the light microscope. Although some of these samples may require staining in order for the observer to see them, the magnification offered by the light microscope is sufficient to look at the morphological structures of the types of cells mentioned above
Does a nucleus have a plant cell or animal cell?
Plant and animal cells have a nucleus. Eukaryotic cells have a nucleus but most bacteria, that aren't eukaryotic, don't have a nucleus.
What is the difference between bacteria and viruses?
Bacteria are single-celled organisms that exist throughout the environment. They live in water, soil, and the air. Bacteria live in and on all animals and plants. Some cause disease, some are beneficial and some have no known impact on the animals they live on or in. Viruses are DNA or RNA, sometimes wrapped in protein coatings. They cannot survive outside a living cell. Viruses cannot reproduce on their own. They use the mechanisms of the living cells they infect to reproduce themselves and in the process they can damage or destroy those cells, causing disease to the animal or plant involved.
What is the simpilist animal form?
bacteria or viruses
What organisms are found in plant and animal cells?
Mostly bacteria and viruses.
What isn't in the animal kingdom?
plants, fungi, bacteria, unicellular organisms
What do animal and plant cells have that bacteria cells don't?
One thing bacteria has that animal and plant cells do not is restriction enzymes for fighting off the attack of viruses.
The relationship of the cell and the microscope?
A cell is a structure which is present inside everything in this world and a microscope is an electronic machine which enables people to see these cells. A cell is classified into plant cell and animal cell and a microscope is classified into electronic microscope and ordinary microscope. Plant cell has cell wall and cell membrane and animal cell has vacuole and nucleus. Electron microscope uses electrons and an ordinary microscope uses simple glass plate. There is also another type of microscope called light microscope which uses light.
What are 5 classes of infectious agents?
Prions, Viruses, Bacteria, Fungi, and Animal Parasites.
What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
Biological contaminants is?
Biological contamination is living organisms such as fungi, viruses, or bacteria. Biological contamination are products that can be hazardous to an animal or human.
What tools do virologist use?
This is not a complete list but a virology lab should have access to An electron microscope (for looking at very small things), A thermocycler (for amplifying DNA using PCR) An ELISA plate reader (another test for detecting viruses.) A What_tools_does_a_virologist_usecentrifuge (used for purifying viruses) For a virologist looking at human and animal viruses they will need test human or animal cells to infect (cell cultures not the animals themselves)- and for a plant virologist test plants to infect.
Viruses are living organisms?
viruses are not living organisms. They simply attach to a cell and when the cell reproduduces the virus is reproduced with the new cells.
What is phagocytize bacteria?
In the process of phagocytosis, phagocytes surround and engulf pathogens (such as bacteria) and use lysosomal enzymes to destroy the germs.
What is the pathogen attacks specific cells and injects genetic materials?
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
