Similar to making a double batch of cookies, in order for a cell to divide it must have double the contents that it normally has. During interphase:

a) None of these happen during interphase; synthesis occurs during Mitosis.

b) Cytoplasm increases, and organelles and DNA are replicated.

c) Cytoplasm and organelles are replicated, but not DNA.

d) Only cellular DNA is replicated to a 4n state.

The cell cycle is divided into two main parts interphase and mitosis. Mitosis is when the cell divides and this process is taken up by the process of dividing. Interphase is broken down into several phases: G1, growth occurs (cytoplasm increases); S, DNA synthesis (replication) occurs; and G2, growth occurs (cytoplasm increases and organelles are replicated). So the answer is b) Cytoplasm increases, and organelles and DNA are replicated
