Dear student,
 
The nucleus is surrounded by a double membrane bearing many pores. These pores are important for cytoplasm-nucleoplasm communication and exchange of materials. Nuclear pores have diaphragms, septa annuli, microspores for movement of substances between nucleus and cytoplasm. The nuclear pore complex was first described by Callan and Tomlin.
