What are disease-causing organisms that are smaller than bacteria?
All the disease causing viruses are smaller in size than bacteria. Rickettsia and chlamydia are other groups of organisms, which are smaller than true bacteria.
What are the 2 microscopic organisms which cause disease?
The two microscopic organisms that cause disease are bacteria and viruses. Bacteria are single-celled microorganisms that can multiply and cause infections in the body, while viruses are smaller infectious agents that can only replicate inside the cells of living organisms.
What are the 4 agents of disease?
The four main agents of disease are pathogens, which include bacteria, viruses, fungi, and parasites. Bacteria are single-celled organisms that can cause infections, while viruses are smaller entities that replicate within host cells. Fungi can cause diseases in both humans and plants, and parasites live on or in a host organism, often causing harm. Together, these agents contribute to a wide range of illnesses and infections.
What type of disease causing organism is so small you must use a microscope to see it?
A virus is a type of disease-causing organism that is so small it can only be seen using a microscope. Viruses are much smaller than bacteria and can only replicate inside living cells.
What are the difference between bacteria cells?
Bacteria are unicellular organisms, which is to say, a bacterium is a cell. Bacteria differ from the cells of multicellular organisms in that they are generally much smaller and less specialized.
What is an amoeba's main food source?
they eat smaller organisms like bacteria
Is a virus is the smallest thing that can cause disease?
Yes, viruses are the smallest known pathogens that can cause disease in humans, as they are much smaller than bacteria and other microorganisms. Viruses rely on host cells to replicate and can infect a wide range of organisms, including humans, animals, plants, and even bacteria.
Are protists smaller than bacteria?
Some protists are larger than bacteria, while others may be smaller. Protists are typically unicellular organisms but can also form colonies or be multicellular, whereas bacteria are unicellular prokaryotic organisms. The size of protists and bacteria can vary greatly depending on the specific species.
What is the size of the bacteria causing periodontal disease?
The size of bacteria causing periodontal disease can vary, but they are generally smaller than 1 micron in diameter. Key bacterial species associated with periodontal disease include Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia.
How did the work of ivanovsky and beijerinck lead to the discovery of the virus?
Ivanovsky and Beijerinck independently discovered that an infectious agent smaller than bacteria was causing disease in plants. Their work laid the foundation for the concept of viruses as distinct entities from bacteria, leading to further research and the eventual identification and characterization of viruses.
Why might a yeast bacteria and a disease causing bacteria differ in size?
Yeast aren't bacteria, they belong to the fungus family. Yeast, like bacteria, only consist of one cell. Bacteria are prokaryotic cells, which a simpler cells (they don't have a cell nucleus, and lack some cell organelles). Because they have less in them, they're smaller. Yeast are eukaryotic cells, meaning they are more complex and have more organelles. To contain them, they have to be bigger.
What are soil bacteria called that break down larger chemicals in dead organisms into smaller chemicals?
what is when soil bacteria break down large chemicals in dead organisms into small chemicals this isn't jepordy, whoever just answered that the answer is decomposers. Yeah I really hate that -_-
