Single-celled, animal-like, eukaryotic organisms of the kingdom Protista. Protozoans can occur wherever moisture exists. There are many parasites and commensals of plants and animals, as well as free-living species. They cause a number of diseases, such as African sleeping sickness, malaria, and dysentery. They are an economically and scientifically important group. It is thought that the organisms of the kingdom Animalia evolved from ancestors which were protozoans.
What else can I help you with?
Select the incorrect statement abount protozoans?
Protozoans are unicellular eukaryotic organisms that can be found in various environments. An incorrect statement about protozoans might be that they are prokaryotic organisms; in fact, protozoans have a defined nucleus and organelles, distinguishing them from prokaryotes like bacteria. Additionally, while some protozoans are autotrophic, most are heterotrophic, relying on other organisms for nutrition.
What is a reproductive body produced by bacteria fungus or some protozoans?
Spore
What is deference between protozoans and bacteria?
Protozoans are eukaryotic, single-celled organisms with complex cellular structures and can be parasitic or free-living, while bacteria are prokaryotic, single-celled organisms that are much smaller in size compared to protozoans and have simpler cellular structures. Additionally, some bacteria can cause diseases in humans and other organisms, whereas protozoans are generally not known to cause diseases.
How many known species of protozoans are there?
There are approximately 30,000 known species of protozoans.
What are the four Phyla of Protozoans?
The four Phyla of Protozoans are Sarcomastigophora, Apicomplexa, Ciliophora, and Microspora.
Harmful effects of Protozoans?
some harmful effects of protozoans is... i don't know you tell me please? :(

Are protists that have chlorophyll protozoans?
yes some of them have. They are doing photosynthesis.
How does protozoans get food?
they get some food in the organisms known as hosts
Are all protozoans prokaryotic and autorophic?
No, not all protozoans are prokaryotic and autotrophic. Protozoans are eukaryotic organisms that can be autotrophic or heterotrophic. Autotrophic protozoans can photosynthesize like plants, while heterotrophic protozoans rely on organic matter for nutrition.
Are protozoans are unicellular or multicellular?
protozoans are unicellular organisms
Do protozoans have skeleton?
No Protozoans do not have skeleton. They are unicellular organisms.
What is a reproductive body produced by bacteria fungus or some protozoans?
Spore
Malaria is caused by these protozoans?
Malaria is produced by parasitic protozoans.
What is study of protozoans known as?
The study of protozoans is part of microbiology.
The fingerlike projections of cytoplasm used by some protozoans for movement and obtaining food are?
The fingerlike projections of cytoplasm used by some protozoans for movement and obtaining food are called pseudopodia. These structures help protozoans to extend their reach and capture food particles in their environment through a process known as phagocytosis.
Why is it important to know about protozoans?
Understanding protozoans is crucial because they play significant roles in ecosystems, serving as both predators and prey in food webs. They can also impact human health, as some protozoans are pathogens that cause diseases such as malaria and amoebic dysentery. Additionally, studying protozoans can lead to advancements in biotechnology and environmental monitoring, given their sensitivity to ecological changes. Overall, knowledge of protozoans enhances our comprehension of biodiversity and ecosystem dynamics.
