The cell nucleus controls all processes within the cell
Cells with a nucleus are called eukaryotic cells, or eukaryotes
Cells without a nucleus are called prokaryotic cells, or prokaryotes
Cells with multiple nuclei are called coenocytic cells, or coenocytes
Some organelles are the evolutionary result of mutual coexistence between prokaryotic and eukaryotic cells
Chapter 2 :
Nucleus
All biological cells store their genetic information in the form of DNA - deoxyribonucleic acid
Eukaryotes store their DNA in their nucleus. Prokaryotes store their DNA in their nucleoid
A nucleus is a roughly spherical, membrane-bound organelle responsible for a cell's growth and reproduction
A nucleus is composed of the following parts: nuclear envelope; nucleoplasm; nucleolus and chromatin
A bacterial nucleoid usually consists of a single molecule of DNA
