PLEASE FEEL FREE TO SING ALONG. . . . LYRICS BELOW:

Living cells are in your brain

Living things are in your veins

Living cells run through your bones

They contain all your chromosomes

Living cells have DNA

Living cells die every day

Animals have em’ and plants do too

Cells make up me and you

Living cells are specialized

They are what make things alive

Living cells have different jobs

In cows and corn on the cob
