Your human body works thanks to cell — trillions of them — doing their jobs. Some make chemistry to hit infection. Others make tears to defend your eyes. Still others make proteins to assist you grow.

You are watching: How is a cell like a factory

You can ask just how this happens. Come understand, think of cells together microscopic factories.

Factories commonly contain people, machines and also raw materials. Provides are brought into the factory. Workers use the offers to construct whatever products the manufacturing facility makes. Devices in the factory play different roles in the process. Everything works together to make commodities customers need.

Cells obtain raw products — consisting of water, oxygen, minerals and other nutrients — native the foodstuffs you eat. They permit in raw products through the cabinet membrane: the thin, elastic structure that forms the border of each cell.

Cells have internal structures called organelles. Each organelle is prefer a worker or a maker that has actually a job to perform for the cabinet to duty properly. Below are few of them.


● The cell nucleus is favor a “foreman,” or human in charge, since it controls cell function. It includes DNA (deoxyribonucleic acid), the grasp organizer for exactly how cells work.

● Mitochondria are the “batteries” in your cells. Chemical reactions in ~ the mitochondria produce the power that powers cabinet functions.

● Lysosomes space fluid-filled vesicles, or sacs, the act as a waste-disposal mechanism for cells. Prefer a hungry Pac-Man, lyosome eat bacteria and unwanted material in the cell. Lock contain enzymes that “digest” anything lock absorb to do it harmless.

● Ribosomes are the cell molecule makers. They assemble protein from amino mountain according come the blueprint in your DNA.

● The absorbent reticulum is a mechanism of tubelike structures that’s crucial for the production of proteins and lipids (fats).

● as soon as protein molecules have actually been made, they relocate to the Golgi device for more processing. The Golgi device is prefer a conveyor belt that “wraps” proteins within vesicles so they deserve to be “shipped” the end of the cell.

To see just how these “factory” parts job-related together, let’s look in ~ the stomach.

In enhancement to making acid to digest food, your stomach contains mucus-producing cells that defend it from being damaged through the acid. The DNA in the cell nucleus instructs the ribosom to do mucus. As soon as this is done, mucus is relocated to the Golgi apparatus. The rubber is climate packaged into vesicles that travel to the cabinet membrane, where it’s released, to coat the lining of her stomach.

As you take the last bite of your breakfast, store the following truth in mind: If those tiny factories in the stomach quit working, your body would certainly be the end of business. That’s because your stomach would certainly digest itself along with your critical meal.
