The section of the cell cycle devoted to division is called M phase, which stands for Mitosis (nuclear division) and Cytokinesis (cytoplasmic division).

Here's a breakdown:

* Mitosis is the process where the duplicated chromosomes are separated into two identical nuclei. This involves several stages: prophase, prometaphase, metaphase, anaphase, and telophase.

* Cytokinesis is the process where the cytoplasm divides, ultimately forming two separate daughter cells.

While M phase is the shortest part of the cell cycle, it's the most visually dramatic and essential for the creation of new cells.
