Nuclear Membrane
Function: Contains the contents of the nucleus while letting proteins and RNA pass in and out.
Present In: Both.
Nucleolus
Function: Contains RNA and proteins, and doesn't contain much DNA.
Present In: Both.
Chromatin
Function: Contains most of the nucleic acids in the nucleus.
Present In: Both.
Centrioles
Function: Helps cell to divide.
Present In: Animals only.
Ribosomes

Chloroplast
Function: Food producers of cell.
Present In: Plants only.
Lysosomes
Function: Holds enzymes created by the cell and can digest stuff.
Present In: Animals only.
Peroxisomes
Function: Holds oxygen-needing enzymes and digests things as well.
Present In: Animals only.
Vacuole
Function: Stores food and nutrients, sometimes even waste.
Present In: Both.
