NucleusLife’s Inner Community cytoplasm Side The _______________ is a double membrane. nuclear pore nuclear envelope

nucleoplasm nucleolus Within the nucleoplasm is a mass of chromatin fibers and the nucleolus. Life’s Inner CommunityNucleus

Life’s Inner Community 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 knot of chromatin. It is the nucleolus that manufactures ribosomes. Life’s Inner Community Nucleus

Life’s Inner Community Nucleus During cell division the nucleus takes on a different appearance.

Cytoplasm The term cytoplasm refers to everything between the cell membrane and the nuclear envelope. Cell membrane/wall Life’s Inner Community 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. Life’s Inner Community

Organelles Life’s Inner Community Gk: Organon – tool, ella – small Besides having a nucleus, what sets eukaryotic celled organisms apart from prokaryotic organisms is that they have tools! organelles !
