When S phase
DNA content doubles, the cell remains diploid right, just like it was before the replication it only doubles the amount of DNA

so chomosome number is the same

In G2 phase, organelles double

G1 phase, gets everything ready for the process

G0 is the arrested phase

I once had a professor who said that G1 was when organelles double, S phase chromosomes double, and G2 is when additional gene productions are made. Had another professor who said we don't fully understand everything that occurs during G2.

G0 is with a banana stand in arrested development though

here is how wikipedia frames it:


G1 (Gap 1), in which the cell grows and functions normally. During this time, a high amount of protein synthesis occurs and the cell grows (to about double its original size) - more organelles are produced, increasing the volume of the cytoplasm. If the cell is not to divide again, it will remain in this phase.

Synthesis (S), in which the cell duplicates its DNA (via semiconservative replication). This is also known as the Swanson phase.

G2 (Gap 2), in which the cell resumes its growth in preparation for division.
