There are a lot of internal organs that a cell has. Theres mitochondria which is the power house/fuel centre of the cell, theres the nucleus which carries the genetic information (DNA), there are ribosomes which produce RNA, then there is the nucleolus, golgi, cell membrane, cilia and flagella for movement, etc…. It pretty well documented on wikipedia. Just search for ‘cell’ on wikipedia. Every organ has its function in a cell and there are plenty! Hope this helped…
One thing I remember is the cell membrane is made up of lipids. This is one reason you don’t need to use antibacterials on everything to kill bacteria. Just using soap or other products which breaks down fats, will cause the germs to fall apart. Or, that is how I learned it, I am not a scientist.
@JLeslie soap does not kill bacteria by interrupting their cell wall. If it did it would also affect the cells that make up your hands as well. What soap does is to act as an emulsifier that help fatty substances to mix with water and so allow them to wash away.
@JLeslie Phospholipids make up cell walls, phosphorous head, lipid tail. The lipid tails are hydrophobic so they’re in the middle of the double layer that makes up cell walls. The cheese in a grilled cheese sandwich. :)
There’s an interesting theory that mitochondria (the energy-generators of cells), and maybe even some other cellular components, may have originated as bacteria that got incorporated into our cells at some far distant point in our evolution.
