Definition
A eukaryote is an organism whose cells contain a nucleus and other membrane-bound organelles. Think of it as a cell with clearly defined rooms for different functions. This is in contrast to prokaryotes, which lack these structures. Eukaryotic cells are generally larger and more complex than prokaryotic cells. Animals, plants, fungi, and protists are all eukaryotes. It's like comparing a well-organized city (eukaryote) to a simple village (prokaryote). 🏘️
