The Cell

A cell can be defined as the protoplasm surrounded by cell membrane, which works as a structural and functional unit of life. The outermost, rigid, protective layer found in cells is known as the cell wall. The non-crystalline, translucent substance found in between the plasma membrane and nucleus is known as cytoplasm.
