Interphase

Interphase

The phase of the cell cycle where the cell spends as much as 90% of its time carrying out metabolic processes.

G1 phase

The first sub-phase of interphase where the cell grows.

S phase

The sub-phase of interphase where DNA synthesis occurs, leading to the duplication of the cell's chromosomes.

G2 phase

The second sub-phase of interphase where the cell prepares to divide.

Metabolic processes

Functions carried out by the cell to maintain life, such as the production of enzymes.

Mitochondria

Organelles that increase in number during interphase as the cell grows.

Ribosomes

Organelles that play a role in protein synthesis and increase in number during interphase.

Cell cycle

The series of phases that a cell goes through from one division to the next.

Key event in S phase

Duplication of the DNA in the cell's chromosomes.

Function of stomach lining cells

Making and releasing enzyme molecules that help digest food.
