Detailed explanation-1: -Nucleus and organelles 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-2: -eukaryotic cells-A type of cell that has a membrane-enclosed nucleus and other membrane-enclosed organelles. All organisms except bacteria and archaea are composed of eukaryotic cells.
Detailed explanation-3: -The nucleus is a membrane-enclosed organelle found in most eukaryotic cells. The nucleus is the largest organelle in the cell and contains most of the cell’s genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it makes up just a small percentage of the cell’s overall DNA content).
Detailed explanation-4: -Definition. The nuclear membrane is a double layer that encloses the cell’s nucleus, where the chromosomes reside. The nuclear membrane serves to separate the chromosomes from the cell’s cytoplasm and other contents.
