The cell wall is the tough, flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. Just as the wall of the factory is for the factory. The wall also is the structure and strength.

The cell membrane that separates the interior of all cells from the outside The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The door and the insulation are the cell membrane. The door is selectively permeable to only workers. The insulation also keeps the inside away from the outside.

The nucleus is a membrane-enclosed organelle found in eukaryotic cells. It contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins. The genes within these chromosomes are the cell's nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell  — the nucleus is, therefore, the control center of the cell. The office is the control center for a factory. It is also where the important information is kept.

The cytoplasm comprises cytosol, the gel-like substance enclosed within the cell membrane – and the organelles – the cell's internal sub-structures. The air in the factory behaves the same way. It brings vital things like oxygen to the workers.

The endoplasmic reticulum (ER) is an organelle of cells that forms an interconnected network around the cell. Its job is to move proteins around the cell. A conveyor belt acts the same way, carrying around the necessary materials .

The Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. The tree making station represents the ribosome because it too makes the necessary products....
