What are the two characteristics of all protozoa
all unicellular (single cell organisms)all are eukaryotes
Protozoa are unicellular organisms that belong to the kingdom Protista. There are many different types of protozoa, but they all share two characteristics:
1. Eukaryotic cells: Protozoa are eukaryotes which means they have a true nucleus and membrane-bound organelles like mitochondria, Golgi apparatus and ER. This distinguishes them from the prokaryotic organisms like bacteria.
2. Heterotrophic nutrition: Protozoa are heterotrophs, which means that they consume other organisms for their nutrition. They can obtain their food either through phagocytosis (engulfing food particles), or by absorption through their cell membrane. Some protozoa are free-living, while others are parasitic.
