Detailed explanation-1: -Detailed Solution. The correct answer is All cells are identical.
Detailed explanation-2: -A prokaryotic cell doesn’t have a nuclear membrane around the nucleus. The nucleus without a nuclear membrane is called the naked nucleus and it is not considered as a true nucleus. So prokaryotic cells don’t have a true nucleus.
Detailed explanation-3: -A nucleus is a double-membrane bounded cell organelle present in eukaryotic cells. It controls the functioning of the cell. It contains chromosomes, through which heredity characters are passed from one generation to the other.
Detailed explanation-4: -The nucleus is surrounded by a double unit membrane from all sites. The chromosomes and genes which have genetical characters and transmit from one generation to another are found in the nucleus. Thus option D is the correct answer.
