Simple cell, Cells that lacks a nucleus and all the membrane organelles
Ex: bacteria
Eukaryotes

Ex: plants, Protists, fungi, animals
Cytoplasm
the cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles.
Cytoplasm has
Organelles, cytoplasmic streaming
Organelles
Small structures inside of a cell
Cytoplasmic streaming
Movement of a cytoplasm
Nucleus
Biggest organelle
Nucleus has
Chromosomes, chromatin, nucleolus, nuclear envelope, nuclear pores
Chromosome
Squiggly lines, only time to see them is during any phase of mitosis. Consists DNA
Chromatin
Dark nucleus, unorganized, the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division.
