Chloroplast
Bean shaped organelle that releases energy from stored food molecules which supplies energy for the cell
Mitochondrion
An organelle that is responsible for making proteins.
Ribosome
A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
Endoplasmic Reticulum (ER)
A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
Golgi Body/Apparatus
