Detailed explanation-1: -Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.

Detailed explanation-2: -In eukaryotic cells, the organelles, including the nucleus, are bound by a membrane. This means that, similar to how the cell as a whole is surrounded by a membrane, different organelles can have different microenvironments suited to their function.

Detailed explanation-3: -Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a well-defined nucleus or any other membrane-bound organelle.
