Answer:

Phases: G1, S phase and G2

Functions:

- G1: cell grows

- S phase: DNA replication

- G1: organelle replication and increase of the cytoplasmatic proteins

Step-by-step explanation:

Interphase is the phase of the cell cycle in which the cell prepares for its division and ensures that each daughter cell has the correct required materials for cell survival (i.e., a correct amount of DNA, organelles, proteins, etc). Interphase can be divided into three subphases: Gap 1 (G1), Synthesis (S), and Gap 2 (G2). During G1 phase, the cell increases its size and replicates its organelles as necessary. During S phase, the cell growth continues, the DNA of the cell is replicated and rapidly assembled into chromatin. During G2 phase, the cell increases its cytoplasmatic content producing molecules it still needs to divide (e.g., essential M-cyclin molecules) and replicates its organelles (e.g., mitochondria in animals and chloroplasts in plants).
