Answer 2

Answer :

The nucleus is one of the most important and the prominent organelles that are present in the cell and in the eukaryotic system the nucleus occupies 10% of the cell volume and performs many important functions.

The nucleus consists of the nuclear envelope, the nucleolus, the chromosomes and the outer layer of the nucleus is connected to the endoplasmic reticulum. The space between the 2 layers of the nuclear envelope is fluid filled.

The nucleus also consists of the holes in its nuclear envelope called the nuclear pores, these pores help in the exchange of large molecules like the RNA and proteins between the cytoplasm and the nucleus.

The chromosomes that are present in the nucleus play an important role in the carrying of information from one generation to another and these chromosomes are the condensed form of genes that code for the characteristics of the organism.
