The cytoplasm contains the cell organelles like mitochondria, ribosomes etc.
(2)Nucleolus and nucleus - The nucleolus is a structure found in the nucleus of cells and it forms around specific chromosomal regions in the nucleus of eukaryotic cells and is made up of proteins and ribonucleic acids. The nucleus is a membrane-enclosed organelle found in eukaryotic cells.
(5)Prokaryotes and eukaryotes - Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
