Here's why:
* Eukarya encompasses all organisms with complex cells that contain:
* True nucleus: A membrane-bound structure that houses the cell's genetic material (DNA).
* Membrane-bound organelles: Specialized compartments within the cell, such as mitochondria, Golgi apparatus, endoplasmic reticulum, lysosomes, etc., each with specific functions.
In contrast, the other two domains of life, Bacteria and Archaea, are prokaryotes. They lack true nuclei and membrane-bound organelles.
