What are the modes of transmission that protozoans can use to cause disease in human?
Protozoans can transmit diseases to humans through various modes, primarily including direct contact, ingestion, and vector-borne transmission. For instance, protozoans like Giardia can be ingested through contaminated water or food, while others, such as Plasmodium, are transmitted via the bites of infected mosquitoes. Additionally, some protozoans can spread through sexual contact or through contact with contaminated surfaces or materials. These transmission routes contribute to the spread of diseases such as malaria, giardiasis, and trichomoniasis.
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.
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 phylum group of protozoans are often parasites?
The phylum group of protozoans that are often parasites include the Apicomplexa, also known as the Sporozoans. These parasites are known for causing diseases such as malaria, toxoplasmosis, and cryptosporidiosis. They have complex life cycles that involve both sexual and asexual reproduction.
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.
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.
Protozoans differ from algae?
Protozoans are heterotrophic, whereas algae are autotrophic.
What makes algae different from protozoans?
Algae are autotrophs, while protozoans are heterotrophs.
What is protozology?
protozology. ology=study of. protoz= protozoans. protozology is the study of protozoans
Why are protozoans called protozoans?
They are called so beecause thes have no cell structure
How many known species of protozoans are there?

What characteristic in the microscopic invertebrates distinguishes them from protozoans?
Protozoans are unicellular and microscopic invertebrates are multicellular
