Question

1. write 3 inferences that can be made from the graph:

time spent in each phase of the cell cycle
percentage of cells (no. of cells) in each phase
g1
s
g2
mitosis
a.
b.
c.

Explanation:

a. The G1 phase takes up the largest portion of the cell cycle, so it is the longest stage for cell growth and preparation.
b. Mitosis is the shortest phase of the cell cycle, meaning cell division happens relatively quickly compared to other stages.
c. The combined length of interphase (G1, S, G2) makes up nearly all of the cell cycle, so cells spend most of their time growing and replicating DNA rather than dividing.

Answer:

a. The G1 phase is the longest stage of the cell cycle.
b. Mitosis is the shortest stage of the cell cycle.
c. Cells spend the vast majority of their cycle in interphase (G1, S, G2) rather than mitosis.
