Fungi are eukaryotic organism whose existence can be traced back to million years ago. They are either unicellular or multicellular. Fungi are heterotrophs, which means, they feed on dead and decaying substances. For this reason, they are called saprophytes.
Fungi remain inside the thread-like structure, namely hyphae. Later on, this hyphal structure matures and forms mycelium. They breed sexually and also asexually through spores formation, branch, budding and fragmentation.
This microbe is widely used to make antibiotics. Some of them are also utilised in baking bread and other edibles. However, also note some fungi are harmful and cause diseases in plants and animals.
You must have seen some blackish-green growth on the bread sometimes. That results from a fungus attack that is responsible for spoiling food. Components of Fungi. A few characteristics of fungi are mentioned below. Golgi bodies. Lysosome and peroxisomes. Cytoplasmic membrane. Endoplasmic reticulum. The following table elucidates the key differences between bacteria and fungi. Points of comparison. Bacteria are unicellular microorganism, coming under prokaryotic classification. It is the most ancient living being on earth with simple cell structure.
Fungi are unicellular organism, coming under the classification of eukaryotic. Notably, they possess a complicated cell structure.
Cells does not contain organelles. Nucleus is absent. Cell wall consists of peptidoglycan. Does contain organelles. Nucleus is present. Cell wall consists of chitin. Three types of shape. Found in different shapes. But usually thread-like called hyphae. Exists below cell wall. It exists in its typical location. Presence of sterols. Absent exception - mycoplasma. This article is meant to provide answers to your questions and offer you information about how viruses, bacteria, and fungi act once they are inside the body.
Some of the most common viruses cause flu and colds. These are easy to treat with modern medication. Nevertheless, others can lead to the development of more serious conditions, such as coronavirus infection. A virus is actually one of the simplest germs , being just genetic material encased in protein. There are ongoing debates among researchers concerning whether a virus is even a living microorganism.
If it exists by itself, a virus can accomplish nothing, as it must enter a living thing to perform the only function it can replicate. It is worthy of note that a virus can infect even bacteria and fungi. When it enters a human body, a virus will hijack the cellular machinery of the individual to create clones of itself, overtaking more and more cells and continuing to reproduce. In the unfortunate case that a virus reproduces at a more rapid pace than the immune system can control it, it will start destroying healthy cells and subsequently harming the body.
A virus is also the smallest of germs, which is why it is so easy to contract one since it can be spread from person to person through the air when coughing or sneezing.
Some viruses are spread through bodily fluids or by mosquitoes. Because viruses are so different, there is no specific medication to counteract the effects it has on your health. Instead, you can prevent viral infection by getting a vaccine against some of the most common viruses, such as polio, hepatitis B, rubella, and measles. The purpose of vaccines is to offer preventive protection from certain viruses by training the body's immune system to identify and attack specific viruses.
It is important to know that antibiotic drugs do not work in destroying viruses. Bacteria are the culprits behind: food poisoning, urinary tract infections, strep throat, and tuberculosis. Interestingly, we have tremendous bacteria colonies in our guts, which actually help strengthen the immune system. When the virus reproduces faster than the immune system can control it, it begins to destroy cells and harm the body.
Viruses are also the smallest germ, making them generally the easiest to contract—they're so tiny they can spread through the air in a cough or a sneeze. Some viruses also are spread by mosquitoes or through bodily fluid.
Since each virus is very different, no one drug exists to attack whichever virus is in your body. Vaccines give preemptive protection from certain viruses by training the body's immune system to recognize and attack a specific virus.
Common forms: Bacteria cause food poisoning, strep throat and urinary tract infections , as well as infections such as tuberculosis. Bacteria are bigger and more complex than viruses, though they can still spread through the air. A bacterium is a single cell, and it can live and reproduce almost anywhere on its own: in soil, in water and in our bodies. For the most part, we live peacefully with bacteria—the colonies in our guts are helpful to us and strengthen our immune system.
But like viruses, bacteria can also harm us by replicating quickly in our bodies, killing cells. Some bacteria also produce toxins which can kill cells and cause an outsized, damaging immune reaction. Broad-spectrum antibiotics were developed to kill bacteria in our bodies and in the food supply by inhibiting their growth. But bacteria are extremely adaptive and can quickly evolve to evade antibiotics.
Bacteria share their antibiotic-resistant genes with each other, meaning more strains generate resistance to the drugs we use. Common forms: Fungi are responsible for causing conditions such as yeast infections , valley fever and meningitis. Fungi are more complicated organisms than viruses and bacteria—they are "eukaryotes," which means they have cells.
Of the three pathogens, fungi are most similar to animals in their structure. There are two main types of fungi: environmental, which are yeast and mold that often live in soil and don't generally cause infection in most healthy people; and commensals, which live on and in us and generally don't hurt us.
