Question

An animal cell is growing and is active. The cell is going through which subphase of interphase?

Answer 1

The three substages of interphase is G1, S, and G2. G1 is the growth phase where the cell will produce the cytoplasm organisms and will synthesize the proteins. The S phase is the synthesis phase where the cell copies the chromosomes while growing. The last phase is the G2 phase where the cell starts to assemble the spindle.

This should help you figure out which one.

Answer 2

G1 phase is the subphase where the cell grows until it becomes too large to preform normal daily activity, and will be sent to the S phase.
