  • It contains a double-layered nuclear membrane which has pores which allow the transfer of material in and out of the cell.

  • It contains chromosomes which contain information for the inheritance of features from parents to the next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules.

  • Chromosome is available in the form of chromatin material in non- dividing cell. Whenever the cell is about to divide, the chromatin material gets organised into chromosomes and perform cell division.
