Is the cell membrane found in plant or animals?

It is actually found in both. In the animal cells, it is the only thing that keeps the material within the cell. And it is semi-permeable so that it only lets in certain objects, molecules and other things of the sort. In plant cells, there is a cell wall that lets close to nothing in through its walls. But there is still a cell membrane, that regulates the objects that do get through. The Cell membrane can be found in both, but usually when you are talking about it, it will usually be associated with animal cells.
