Answer:
1. flagella
2. chlorophyll
3. parasitic
4. Scientists have recently rejected "Protista" as a kingdom because as evolutionary and molecular knowledge continues to increase, the relationships among organisms are strengthened that weren't previously considered. It continues to be found that many protists don't share common ancestry with other protists that don't exclude other groups, such as plants, animals, and fungi. Protists had been previously classified through what they are not: plants, fungi, or animals. They share no characteristics that aren't also shared by "nonprotists."
5. The three main ways protists can move are through cilia, flagella, and pseudopods. All of these structures help protists to move in different ways through their environment.
6. The eukaryote that causes red tide is known as a dinoflagellate.
7. The eukaryotes that push carbon to the bottom of the ocean are known as diatoms. This is important to the ecosystem because it lowers the overall carbon dioxide levels in the air and buries the carbon deep in the sea.
8. The endosymbiotic theory posits that eukaryotes emerged when one or more prokaryotic cells ingested another prokaryotic cell, leading to the eventual eukaryotic cell.
