Mocro Organisms Friend Or Foe

all the given are microorganisms

Cold and flu are caused by viruses. Viruses are tiny infectious agents that invade and multiply within the cells of the body. They can cause respiratory infections like the common cold and flu by infecting the respiratory system. Bacteria, protozoa, and fungi are not responsible for causing cold and flu.

Tuberculosis is caused by bacteria. Bacteria belonging to the Mycobacterium tuberculosis complex are responsible for causing tuberculosis. These bacteria can be transmitted from person to person through the air when an infected individual coughs or sneezes. Once inhaled, the bacteria can infect the lungs and other parts of the body, leading to the development of tuberculosis. Treatment for tuberculosis typically involves a combination of antibiotics to kill the bacteria and prevent the spread of the disease.

Amoeba can live alone because they are single-celled organisms that can survive and carry out all necessary life functions independently. They can obtain nutrients, reproduce, and respond to their environment on their own. Amoebas are capable of engulfing and digesting food particles, and they can also undergo a process called binary fission to reproduce. Therefore, they do not require any other organisms for their survival and can live alone.

Normally we cannot see these living organisms but some organisms like fungus on bread., we can see.

Bacteria are indeed single-celled organisms. Unlike multicellular organisms, bacteria consist of only one cell, which is capable of carrying out all necessary functions for survival and reproduction. This single cell contains all the necessary organelles and structures to perform essential processes like metabolism, growth, and reproduction. Bacteria are incredibly diverse and can be found in various environments, including soil, water, and even inside the human body. Their single-celled nature allows them to adapt and thrive in a wide range of conditions.

Typhoid is caused by bacteria. Bacteria, specifically Salmonella typhi, is responsible for causing typhoid fever. This bacterial infection is typically contracted through contaminated food or water. The bacteria enter the body through the digestive system and then spread to the bloodstream, causing symptoms such as high fever, abdominal pain, weakness, and fatigue. Treatment usually involves antibiotics to eliminate the bacteria from the body.

Viruses are microscopic infectious agents that can only reproduce within living cells. They are unable to reproduce in the atmosphere or substances like water, as they require a host organism to replicate. Viruses have specific target cells in humans and animals where they can enter, hijack the cellular machinery, and produce multiple copies of themselves. This ability to reproduce within host organisms is what enables viruses to cause diseases and spread from one individual to another.

Malaria is caused by protozoa. Protozoa are single-celled organisms that belong to the phylum Apicomplexa. The specific protozoan parasite responsible for malaria is Plasmodium. It is transmitted to humans through the bite of infected female Anopheles mosquitoes. Once inside the human body, the parasites multiply in the liver and then infect red blood cells, leading to the characteristic symptoms of malaria, including fever, chills, and flu-like illness. Treatment and prevention strategies for malaria primarily focus on targeting the protozoan parasite.

Algae and fungi exhibit diverse forms in nature. Algae can exist as single-celled organisms, like certain types of phytoplankton, or as multicellular forms, such as seaweed. Similarly, fungi can be unicellular, like yeasts, or multicellular, forming complex structures like mushrooms. This dual ability to exist in both single-celled and multicellular forms distinguishes algae and fungi as versatile organisms in various ecosystems.

Dysentery is caused by protozoa. Protozoa are single-celled organisms that can infect the intestines and cause inflammation, leading to symptoms such as diarrhea, abdominal pain, and blood in the stool. Common types of protozoa that cause dysentery include Entamoeba histolytica and Giardia lamblia. These organisms are usually transmitted through contaminated food or water, and they can multiply and spread within the intestines, causing severe gastrointestinal symptoms. Treatment typically involves medications to kill the protozoa and alleviate symptoms.

Colds are caused by viruses, specifically rhinoviruses, while tuberculosis is caused by bacteria, specifically Mycobacterium tuberculosis. Viruses are tiny infectious agents that can only replicate inside the cells of a living organism, causing various symptoms such as a runny nose, sore throat, and cough in the case of a cold. On the other hand, bacteria are single-celled microorganisms that can reproduce independently and cause more severe diseases like tuberculosis, which primarily affects the lungs but can also affect other parts of the body.
