Part 4: Cells Song

Lyric

Meaning

Well I have a theory Schleiden, Schwann, & Virchow agree with

​

That all living things have basic cells, yeah Anton believes it

​

The first to see it, Hooke was wow’d by a cork, When he put it under a microscope

​

Plants have cellular walls, but we don’t need them at all

​

Our little membranes are flexible and strong

​

They pack their vacuoles in

​

With chloroplast they begin Collecting sunlight Afraid of the dark again

​

Now I gain control, grab the joystick and manage the nucleus

​

Deciding what comes in there and who should leave –it’s exclusive access

​

Genetic glow sticks Provided by the chromatin

​

The nucleolus brings the ribs

​

Outside the envelope, waiting in the cytoplasm

Lyric

Meaning

The mitochondria treat you like a meal

​

While they try to convert you into something real – tasty

​

The longer you stand, waiting in the cytoplasm Lysosomes look at you like you’re bacteria…

​

They’re little round structures filled with chemicals that don’t feel Aiming to break you down

​

Mr. Nucleolus brings the ribosomes that make proteins

​

They take an endoplasmic trip around the cell on reticulum 19

​

You know they’re received Cause the golgi bodies put them in these vesicles

​

And fill the need

​
