1. Presence of a nucleus:
* Eukaryotic cells have a true nucleus enclosed within a membrane, where their DNA is stored.
* Prokaryotic cells lack a nucleus. Their DNA is located in a region called the nucleoid, which is not enclosed by a membrane.
2. Organelle complexity:
* Eukaryotic cells have membrane-bound organelles like mitochondria, Golgi apparatus, endoplasmic reticulum, etc., which perform specific functions.
* Prokaryotic cells lack these complex organelles. They have only a few basic structures, like ribosomes, and their functions are performed by the cell membrane and cytoplasm.
