Nucleus

Within the nucleus is found chromatin and a structure called the nucleolus. Chromatin is DNA in its active form. It consists of DNA looped around histone proteins.

The nucleolus is a knotof chromatin. It is the nucleolus that manufacturesribosomes.

Cytoplasm

The term cytoplasm refers to everything between the cell membrane and the nuclear envelope.

The term hyaloplasm refers to only the fluid part of the cytoplasm.

Cytoplasm

The cytoplasm consists of primarily of water, salts (ions), organic monomers and polymers, the building blocks of large macromolecules. It also contains various organelles as well as dissolved gasses and nutrients.

organelles !

Gk: Organon – tool, ella – small

Besides having a nucleus, what sets eukaryotic celled organisms

apart from prokaryotic organisms

is that they have tools!
