Within the microcosm of our being, tiny worlds reside,
Cells, the architects of life, where mysteries abide.
In their silent, ceaseless dance, existence is revealed,
Each one a universe, a secret gently unsealed.

The nucleus, a command center, guiding with precision,
Mitochondria, powerhouses, fueling life’s mission.
Membranes form the walls, both sturdy and flexible,
In this intricate domain, all is interconnected and sensible.

Chromosomes of heritage, threads of our design,
DNA, the script, where life’s patterns intertwine.
Through mitosis and meiosis, the old and new combine,
A cycle of renewal, with roles so well-defined.

Cells, the unseen artists, crafting all we know,
From single-celled beginnings, to complex beings that grow.
They whisper tales of history, and futures yet to show,
In every breath and heartbeat, their legacy they bestow.
