1. What is the domain?Eukarya, encompassing all organisms with complex cells
2. What is the estimated origin?Approximately 2 billion years ago, following endosymbiotic events
3. Why do eukaryotic cells have a nucleus?The nucleus keeps the cell’s DNA safe and lets the cell copy and read its genes before making proteins in the rest of the cell.
4. How did eukaryotes get mitochondria and chloroplasts?They came from tiny bacteria that were eaten by bigger cells and became helpful partners, giving the cells more energy and the ability to use sunlight.

Endosymbiosis: A symbiotic relationship where one organism lives inside another, leading to evolutionary integration.
Organelle: A specialized subunit within a cell that has a specific function.
Protist: A diverse group of single-celled eukaryotic organisms that are not animals, plants, or fungi.
