Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller?

Cells only need to grow in size and contents before each cell division so as to avoid getting smaller in size with successive divisions.

Each of the daughter cells produced during mitotic cell division goes through an interphase period. The interphase period is divided into 3:

Without going through the stages above, a cell will simply go into a dormant phase which is essentially a resting phase.

Grow

Explanation:

Before every cell division, cells replicate their DNA to pass on to the daughter cells. They also grow in size and replicate their organelles to ensure that each daughter cell has sufficient resources to carry out all the activities necessary for its function. They also ensure there are sufficient nutrients to perform their tasts.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
