Protozoa

Protozoa are single-celled organisms that belong to the kingdom Protista. They are found in various aquatic and terrestrial environments and can be free-living or parasitic. These microorganisms play a crucial role in the ecosystem as they serve as food for many other organisms and also act as decomposers.

Characteristics of Protozoa

• Single-celled organisms
• Eukaryotic, meaning they have a true nucleus and organelles
• Mostly motile, using structures like cilia, flagella, or pseudopodia for movement
• Reproduce asexually through binary fission or sexually through conjugation
• They can be parasitic or free-living
