CYTOPLASM
Cytoplasm is the ground substance present between plasma membrane and nucleus of all cells excepting viral cells. It is an amorphous, translucent, homogenous, colloidal substance, differentiated into cytoplasmic matrix and cytoplasmic structures. Cytoplasmic matrix, hyaloplasm, or cytosol is differentiated into peripheral denser and non-granular part called cortex or ectoplasm and inner less denser and granular part called medulla or endoplasm. It is a true solution of nucleotides, vitamins, RNAs, minerals, sugars, amino acids and colloidal solution of proteins. Cytoplasmic structures include cell organelles.
NUCLEUS OF THE CELL
The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Cytoplasm is a semi fluid matrix present in both prokaryotic and eukaryotic cells. It is the main arena of cellular activities as it where the cell organelles are found.
