Final answer:
Eukaryotic cells have a nucleus surrounded by a complex nuclear membrane and possess membrane-bound organelles in the cytoplasm. They package their DNA in multiple rod-shaped chromosomes. These characteristics are common in eukaryotic organisms including protists, fungi, plants, and animals.
Step-by-step explanation:
Eukaryotic cells have several characteristics in common. First, they have a nucleus surrounded by a complex nuclear membrane, which distinguishes them from prokaryotic cells. They also have membrane-bound organelles in the cytoplasm, such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. Eukaryotic cells package their DNA in multiple rod-shaped chromosomes, unlike prokaryotic cells which have a single circular-shaped chromosome. These characteristics are found in eukaryotic organisms including protists, fungi, plants, and animals.
