NEET BIOLOGY

Detailed explanation-1: -The nuclear envelope separates the contents of the nucleus from the cytoplasm and provides the structural framework of the nucleus. The nuclear membranes, acting as barriers that prevent the free passage of molecules between the nucleus and the cytoplasm, maintain the nucleus as a distinct biochemical compartment.

Detailed explanation-2: -The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

Detailed explanation-3: -Nuclear Membrane 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.

Detailed explanation-4: -The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope.

Detailed explanation-5: -The nucleus is a double-membrane bound cell organelle that is located in the eukaryotic cells and composes of the cell’s genetic material – the DNA.
