Separating a cell into 2 different parts allows for the creation of specific environments in a cell.One example would be Nuclear Envelope.The nuclear envelope is a double membrane Where the two membranes are separated by space.Another example would be the Endoplasmic Recticulum. The endoplasmic recticulum has two different parts which are the smooth er and the rough er. The smooth er is smooth at the top because it lacks ribosomes.The rought er is rough because it has studded ribosomes on the outer surface of the membrane.
