I went into a cell, to get out of the rain,
and there was the gatekeeper, the cell membrane.
I went into a cell, and what did I see,
the mitochondria, it's the energy factory.
I went into a cell, and said "who drives this bus"
and found myself talking to the boss, the nucleus.
I went into a cell, to recover from a spasm,
and found myself swimming in some clear cytoplasm.
I went into the nucleus to ask how to get home,
and got genetic info, stored in a chromosome.
I went into a cell, and stretching o' so far,
was a thin and wavy network, it's called the E.R.
I went into a cell, trying not to be perplexed,
by the packaging and sorting in the Golgi complex.
I went into a cell, and said "who makes proteins here?"
and somebody responded "it's the ribosome, my dear."
I went into a cell, and was feeling pretty fine,
till a lysosome engulfed me, and dissolved me in enzymes.
I went into a cell, and was feeling pretty nimble,
till a centriole lassoed me, tying me up in a spindle.
I went into a plant cell to see how trees get so tall,
and all around the outside was a rigid cell wall.
I went into a plant cell, "why's it so green I asked?"
"'Cause I make food from sunlight," said a green chloroplast.
I went into a plant cell to see how plant cells store food,
when a vacuole informed me that he was the storage dude.
So when you go inside a cell, remember what you see,
There's over a trillion cells in both you and me.
Just sing this song if you ever feel confusion,
and remember active transport is the opposite of diffusion.
