No, there is no mitochondria in viruses. Mitochondria are organelles that are only found in eukaryotic cells, which are biologic cells that have a distinct nucleus which contains the genetic material bound in a membrane.
Viruses, however, are not considered living organisms and do not contain any structures analogous to organelles. Instead, they contain a protein coat and a nucleic acid core composed of either DNA or RNA, but no cellular structure.

Do viruses and bacteria have mitochondria?
No, viruses and bacteria do not have mitochondria. Mitochondria are membrane-bound organelles found in eukaryotic cells, which are cells with a nucleus and other membrane-bound compartments. Viruses and bacteria do not have membrane-bound compartments, including a nucleus, so they also do not have mitochondria.
Mitochondria are commonly known as the “powerhouses of the cell” because they are responsible for the production of energy (ATP) in organisms. Viruses and bacteria do not need their own source of ATP production because they can rely on the host cell’s mitochondrial machinery.
Which organelles is absent in virus?
Viruses are not considered living organisms because they lack certain characteristics that are found in living cells, including the presence of organelles. Organelles are specialized structures within cells that carry out specific functions.
Examples of organelles include the nucleus, which houses genetic material, the endoplasmic reticulum, which manufactures proteins, and the mitochondria, which produces energy. Viruses lack these and other organelles, instead consisting of protein shells that contain genetic material.
Viruses cannot carry out the same processes as living cells, such as physiological and metabolic functions, so they rely on their hosts for survival. The lack of organelles makes it difficult to classify viruses as living organisms since they lack the basic components necessary for independent existence.
Are ribosomes found in viruses?
No, ribosomes are not found in viruses. Ribosomes are structures within cells that read coded genetic messages from molecules of messenger RNA (mRNA) and translate these messages into proteins. While viruses are made of genetic material, they lack the full compliment of cell structure and organelles that a typical cell possess, including ribosomes.
Viruses require a host cell that contains ribosomes, in order to create more copies of themselves. A virus will only be able to replicate if it can gain access to the host cell’s ribosomes, where the virus’ genetic material is “read” and used to create more viruses.
What organelles do viruses contain?
Viruses do not contain any organelles as they are not a cell. Instead, they are made up of a nucleic acid (DNA or RNA) surrounded by a capsid. The capsid is a protein shell that holds the genetic material and protects it from the environment.
Additionally, some viruses have an outer lipoprotein layer, called an envelope, which is composed of lipids and proteins. The envelope helps the virus to enter host cells.
Do all viruses use ribosomes?
No, not all viruses use ribosomes. Different types of viruses have adapted different ways of reproducing and may not use ribosomes at all, instead relying on other organelles within the cell to carry out their replication.
For example, DNA viruses, like herpes and viral hepatitis, are replicated by DNA-dependent RNA polymerase enzymes that copy the viral genome without the need for ribosomes. Furthermore, some viruses, such as retroviruses, actually rely on the host cell’s ribosome to produce their proteins and carry out the genetic instructions of their genome.
So while ribosomes are essential to some viruses in the replication process, they are not essential to all viruses.
Do viruses have nucleus or organelles?
No, viruses do not have nuclei or organelles. Viruses are acellular, meaning that they are non-living particles consisting of genetic material surrounded by a protein coat. They do not contain a nucleus or any other organelles as they are not living organisms.
Instead, viruses depend upon host cells to reproduce, as they lack the machinery necessary to replicate on their own. When a virus enters a host cell, it injects its genetic material into the host’s genome, hijacking its reproductive machinery to produce more copies of itself.
The newly created viruses are then released and are free to go infect other cells.
Do viruses have a cell membrane and DNA?
No, viruses do not have a cell membrane or DNA. Viruses are not considered living organisms because they are not made of cells and cannot reproduce on their own like other living things. Instead, viruses are a form of non-living infectious agents composed of genetic material, like DNA or RNA, surrounded by a protective coat of protein.
This protein coat is what helps the virus bind to and enter a host cell and begin the infection process. As a result, viruses have no cell membrane and do not contain the biochemical processes necessary to produce and replicate DNA or other genetic material.
Can organelles be found in bacteria?
Yes, organelles can be found in bacteria. Organelles are found in both eukaryotic and prokaryotic cells and bacteria are a type of prokaryotic cell. The organelles found in bacteria are referred to as bacterial organelles or inclusions.
Bacterial organelles have specific functions which vary from species to species, but include things such as energy production, cell signaling, DNA replication, nutrient storage, and protein production.
Examples of bacterial organelles include carboxysomes, gas vesicles, magnetosomes, sulfur globules, and flagella. Carboxysomes increase the efficiency of the carbon dioxide concentrating mechanism in some bacteria, gas vesicles serve as buoyancy aids to help the organism maintain its position in water, and magnetosomes are used to align the bacteria in the Earth’s magnetic field.
Sulfur globules are involved in sulfur metabolism in sulfate-reducing bacteria, and flagella provide motility and move the bacteria.
What do bacteria and virus have mitochondria?
No, bacteria and viruses do not have mitochondria. Mitochondria are specialized organelles (a type of cellular component) present in most eukaryotic cells, meaning they are not found in bacteria or viruses, which are both prokaryotes.
Mitochondria play an important role in generating energy for a cell, and some theories suggest that mitochondria evolved from bacteria. Therefore, bacteria do not contain mitochondria and viruses do not contain mitochondria because they are not able to produce or use energy like eukaryotic cells can.
How does mitochondria help the immune system?
Mitochondria plays a vital role in helping the immune system by providing energy to cells and by producing molecules that act as signaling molecules for the immune system. Mitochondria produce energy by breaking down glucose into molecules of ATP (Adenosine Triphosphate).
ATP is used for various metabolic processes, including cell growth and replication. Without ATP, cells of the immune system would not have enough energy to function properly and processes such as cellular signaling and phagocytosis would not be able to take place An additional function of mitochondria is to create signaling molecules, such as cyclic AMP (cAMP) and cyclic GMP (cGMP), that help coordinate the immune system’s activities.
For example, cAMP is used to activate the production of cytokines, small protein molecules that are involved in the communication between cells of the immune system that help regulate the body’s response to infection.
Finally, mitochondria can also produce reactive oxygen species that help the immune system to recognize and destroy foreign or invading cells. Reactive oxygen species also help activate the production of cytokines and can act as a defense against invading pathogens.
Thus, mitochondria ensures the proper functioning of the immune system by providing energy and by producing important signaling molecules and reactive oxygen species.
Why can’t viruses make their own energy?
Viruses are not living organisms, so they do not possess the capability to make their own energy. Unlike bacteria and other living organisms, viruses are not composed of cells that contain their own metabolic machinery which allows them to produce energy.
Instead, viruses rely on their host cell’s metabolic machinery to reproduce. They inject their genetic material, in the form of viral DNA or RNA, into the host, hijacking the cell’s metabolic and reproductive processes to create hundreds of new viruses.
In essence, viruses do not possess the necessary biological structures to produce energy on their own, and therefore, cannot make their own energy.
Does a virus need a mitochondria ribosomes or nucleus How do you know?
No, a virus does not need a mitochondria, ribosomes, or nucleus in order to exist and replicate. Viruses are not considered living organisms because they cannot perform any of the functions of living organisms, such as using energy from the environment, taking in nutrients, responding to stimuli, or reproducing independently.
Viruses are composed of genetic material (DNA or RNA) enclosed in a protective jacket of protein or lipids. This structure is known as a capsid or nucleocapsid and is different from the nucleus, mitochondria and ribosomes that are present in living organisms.
The capsid is what helps a virus to attach to host cells and inject its genetic material, allowing it to replicate and cause disease.
Why is mitochondrial important?
Mitochondria are important because they are the powerhouses of the cell and are responsible for producing energy. Specifically, they generate energy in the form of ATP (adenosine triphosphate), which is then used by all of the other organelles and processes in the cell for growth and maintenance.
They are capable of generating energy through aerobic respiration, which is an efficient process that allows the cell to produce a lot of energy. Without mitochondria, many of the vital functions of the cell would be impossible to carry out.
Additionally, mitochondria are involved in a variety of other cellular processes, such as signaling pathways and the accumulation of calcium ions. All together, mitochondria are essential for proper cell functioning, making them an important and integral part of the cell.
