Detailed explanation-1: -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-2: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.
Detailed explanation-3: -Eukaryotic cells contain a true nucleus where DNA is found. Examples of eukaryotes include all plants, animals, and fungi. The organisms in Domains Bacteria and Archaea are prokaryotic, meaning that their cells do not have a true nucleus, but rather have a nuclear region.
Detailed explanation-4: -A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus, ” alluding to the presence of the membrane-bound nucleus in these cells.
Detailed explanation-5: -Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.
