In the heart of our being, tiny wonders roam, Cells so small, they build our home. Nucleus, the brain, where the plans are laid, DNA spirals, our genetic cascade. Oh, human cells, you're the spark of life, In every breath, in every stride. From head to toe, you're the ones who thrive, Oh, human cells, in you, we survive. Mitochondria, powerhouse, energy ignite, ATP flowing, keeping everything right. Ribosomes crafting, proteins align, In this cellular world, everything's by design. Oh, human cells, you're the spark of life, In every breath, in every stride. From head to toe, you're the ones who thrive, Oh, human cells, in you, we survive. Membrane's the barrier, keeping balance tight, With channels and gates, letting signals in flight. Cytoplasm's the sea, where reactions occur, In this microscopic dance, life is a blur. Lysosomes breaking down, cleaning up the mess, Golgi bodies packaging, sending out express. Stem cells growing, transforming with grace, In this symphony of cells, we find our place. Oh, human cells, you're the spark of life, In every breath, in every stride. From head to toe, you're the ones who thrive, Oh, human cells, in you, we survive. So here's to the cells, the unsung stars, In the universe within, they're who we are. Microscopic warriors, day and night, In the story of life, they're our guiding light.
