<h3>What is a Protist?</h3>
- Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist.
- The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.
- Protozoa is another name for protists that resemble animals. Some are parasites as well.
- The four phyla that make up the Protozoa are flagellates, ciliates, spore-forming protists, and protists that resemble amoebas.
- Nuclear membranes surround the DNA of protists.
- Most protists are motile, or able to move, and many of them inhabit aquatic settings.
- Protists can reproduce sexually and/or asexually, and their life cycles are intricate.
- Protists consume, absorb, or produce food through photosynthesis.
