What is a protoplast? I know that it is a part of the cell wall. So is the cell membrane on the inner side of the protoplast? During plasmolysis, does the protoplast pulls away or does the cell membrane pull away from the cell wall? The book I am referring to says that the protoplast is "living". What do they mean? The cell is a living thing, but are the organelles individually living things? What makes the protoplast living and not another organelle of the cell a living component?
