Nucleus: Is the “brain” of the cell. It controls cells’ functions and it contains DNA.

Cell membrane (plasma membrane) :Allows for certain things to enter and exit the cell. It maintains cell’s homeostasis.
Ribosomes: Make proteins for the cells
Mitochondria: “power house of the cell”, this is where cells receive their energy.
Cell Wall: Supports and protects plant cells.
Chloroplast : Where plants absorb sunlight, and make food (carbohydrates).
