Which of these is not an example of how substances move within cells?

Answer:
Diffusion
Explanation:
Diffusion is the process of transporting substances through the cell membrane. The cell membrane is semi permeable, which means it only allows certain substances to exit and enter the cell. Substances move from a high concentration to a lower concentration without the use of energy.
Cell cycle is not an example of how substances move within cells. Thus, option D is correct.
A cell cycle is a series of events that takes place in a cell as it grows and divides. The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
Cell cycle is responsible for growth of cell not for the any substance movement within cell. Thus, option D is correct.
