what are some similarities between bacteria and viruses?

Bacteria and viruses are both microscopic microbes. Both of them can cause diseases in plants and animals. Both these types of microbes contain enzymes required for the DNA replication and protein synthesis. But, viruses require a host organism for the production of viral coat proteins.

Cells of Bacteria: The cells of bacteria are different from those of plants and animals in many ways, the most obvious of which is that bacteria lack a nucleus and other membrane-bound organelles (except ribosomes). Unlike animals and plants, bacteria have pili, flagella, and most have a cell capsule.

Bacteria are prokaryotic cells; fungi, protozoa, algae, plants, and animals are composed of eukaryotic cells. 7. Viruses are not cells so they are neither prokaryotic nor eukaryotic. They can replicate only inside a living cell.

Unlike viruses, bacteria can grow on the food they contaminate. Most foodborne illnesses come from bacteria. A virus is non-living, and is usually spread from person to person. While some antibiotics may be used to treat bacterial infections, they are ineffective with viral ones.

Bacterial infections are caused by bacteria, while viral infections are caused by viruses. That's the easy part. Differentiating between the two requires medical intervention since both may cause fever and irritability. And the treatments vary significantly.

And how are they different to our most body cells. ... Short story: Human cells are eukaryotic which means they are more complicated, bacteria cells are prokaryotic which means they are simpler and viruses are not even cells at all, they are just genetic material in a protein shell.

A bacterium is a single cell organism, some of which are pathogenic, which infect mammals and cause disease. Bacteriophage are viruses that specifically infect bacteria and kill the bacterium during the process of producing more bacteriophage.

Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria's genome, but much smaller.

Answer: Viruses are non-living features intermediate between non-living and living organisms. On the basis of characters, such as non-cellular organization, inactivity outside the host organism, lack of respiration and cellular metabolism, these are caused non-living.

Answer From James M. Steckelberg, M.D. As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.

Viruses can replicate only by infecting a host cell. They cannot reproduce on their own. Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes.

A bacteriophage is a virus that infects bacteria A bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material. ... The capsid of a bacteriophage can be icosahedral, filamentous, or head-tail in shape.

Summary. Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.

While both can cause disease, viruses are not living organisms, whereas bacteria are. Viruses are only "active" within host cells which they need to reproduce, while bacteria are single-celled organisms that produce their own energy and can reproduce on their own.

Answer and Explanation: Viruses are unique organisms. They do not belong to any kingdom due to the fact that they are not made up of living cells.

Viruses are considered to be nonliving. ... Viruses resemble organisms because they can multiply. They are different because they are not alive: they are not cells, they do not use their own energy to grow or respond to their surroundings.

All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. In most cases, they reprogram the cells to make new viruses until the cells burst and die.
