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: -The Nucleus & Its Structures Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Detailed explanation-3: -Of all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell’s DNA is housed and the process of interpreting it begins.

Detailed explanation-4: -Nucleoli are present in almost every eukaryotic cell type and represent the most prominent compartment of the cell nucleus. The primary function of the nucleolus consists in ribosomal RNA (rRNA) transcription, rRNA processing and ribosome subunit assembly (Hernandez-Verdun et al.

Detailed explanation-5: -A eukaryotic cell has a nuclear membrane. It has mitochondria, Golgi bodies, cell wall. It also contains locomotory organs such as cilia and flagella. The nucleus has a DNA that carries all the genetic information.
