Organs are made up of many cells. Unicellular organisms by definition have only one cell, so they can't have organs.
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
yes protozoa is a type of unicellular organisms?
Sporozoan are unicellular organisms. It's classified into the Kingdom Protista, which are single-celled organisms.
Unicellular organisms are the organisms which have only on cell as the body eg: Amoeba, This is a unicellular organism which can perform all functions just like a multicellular animal. It performs respiration without any organs just like a multicelluar animal which has respiratory organs(Gills, lungs etc). and also reproduction, excretion, circulation, etc. A multicellular animal has many cells(Millions, trillions of cells) these cells are grouped to form tissues which perform a similar function (ie all the cells in a tissue perform similar function) The tissues are organized to form organs (Liver, Pancreas, Muscles etc). There are many differences between a unicellular organisms and multicellular organisms.
how unicellular organism survive
No,unicellular organism is composed of only one cell and every tissue is a group of cells which are organized in a proper way to carry out a specific function.Tissue can only be found in a multicellular organism not in a unicellular organism.
Three differences between unicellular and multicellular organisms is that unicellular organisms are microscopic and can live in extreme temperatures. Multicellular organisms are much larger and have systems and organs.
Staphylococcus Aureus, Amoeba, Paramecium, Vorticella
One cell organisms are called unicellular. does that answer your question?
No. An example of unicellular organisms would be bacteria. Earthworms are multicellular and contain organs and organ systems. Unicellular organisms are typically invisible to the naked eye except when in large groups (such as yeast).
Unicellular organisms contain only one cell. Within a single cell, you can't have levels of organization like tissues, organs, and organ systems.
Both unicellular cell and Body cell, specifically in the nose, have the structure called Cilia. Some unicellular cells use it for locomotion (mobility). On the other hand, humans use it as filter in their nose. They are the small hairs in human nose..
Most of the unicellular organisms reproduces asexually.
Diseases do not cause unicellular organisms; unicellular organisms cause diseases.
Colonies of unicellular organisms can work together.
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
Unicellular organisms evolved first; and from them evolved the multicellular organisms. But that leads onto another question as to why multicellular organisms evolved.
