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: -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: -The answer to this is no, not all eukaryotic cells will have just a single nucleus. Some eukaryotic cells will form what is called a syncytium, where multiple nuclei will be found within the cell’s cytoplasm.

Detailed explanation-4: -Only the cells of advanced organisms, known as eukaryotes, have a nucleus. Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae. Simpler one-celled organisms (prokaryotes), like the bacteria and cyanobacteria, don’t have a nucleus.

Detailed explanation-5: -RBC and platelets present in eukaryotes also do not have the nucleus. It’s RBC (Red Blood Corpuscles) and platelets.
