which is a reason why cells remain small?

• large cells have difficulty diffusing nutrients rapidly enough.

• as cells grow, their ratio of surface area to volume decreases.

• transportation of wastes becomes a problem for large cells.

• all of the above.

which describes the activities of a cell that include cellular growth and cell division?

• chromatin.

• mitosis.

• cytoplasm.

• cell cycle.

what is the role of cyclins in a cell?

• to control the movement of microtubules.

• to signal for the cell to divide.

• to stimulate the breakdown of the nuclear membrane.

• to cause the nucleolus to disappear.
