This is a bit of a riddle! Here's how to break it down:

* Cell cycle: The process of a cell growing and dividing.

* "Say" can be interpreted as what the cell is "doing" or "performing" during its cycle.

So, the answer to the riddle is:

The cell "says" it's "growing and dividing"!

This is a playful way to describe the cell cycle's core function: creating new cells for growth and repair.
