IB Biology Topic D2.1.14 Cell Growth During Interphase Revision Notes (HL) | RevisionDojo

Written by official IB examiners

Interphase Is a Busy Growth Phase, Not a Rest Stop

During interphase the cell is metabolically active and grows steadily.
It is a common mistake to call it a resting phase, because the cell is constantly carrying out biosynthesis.
Interphase covers the G1, S and G2 phases, which is where all this growth takes place.
By the time the cell divides, it has grown large enough for each daughter cell to be a viable size.

Common Mistake

Interphase is not a pause in the cell cycle.
It is the growth period that prepares the cell to divide.

Growth Happens Through Biosynthesis

The cell roughly doubles its size and mass across interphase.
This growth depends on biosynthesis, the building of new cell components.
There are three main things the cell makes more of: proteins, DNA, and organelles.
