Answer
Nucleus is the most important part of the eukaryotic cell.
Inside the nucleus there is round darkly stained nucleolus.
The nucleus is covered over by double membrane which is porous.
The nuclear pores allow the transport of different substances in and out of the nucleus to cytoplasm.
Inside the nucleus is the chromatin network which contains chromosomes. Chromatin fibres are thin which condense to form chromosomes. The chromosomes become clear and distinct at the time of cell division.
In every cell there are specific number of chromosomes. Chromosomes contain genes which are bearers of hereditary characters.
