You are the unicellular dinoflagellate algae, I am the Host Organism

I was the MC at the PDC talent show. One guy stood up and read this while another guy played guitar. It keeps popping into my head

You are the blossom,
I am the vine,
You are the blossom,
I am the vine,

Sweet Little Blossom of Mine,
Hanging on the vine,
Extracting all the nutrients from inside,
Sweet Little Blossom of mine,

You are the Oyster,
I am the Pearl,
You are the Oyster,
I am the Pearl

Sweet Little Oyster of mine,
Irritating you from inside,
Covering me with your mucus-like substance until I shine,
Sweet Little Oyster of mine.

I am the Host Organism,
You are the unicellular dinoflagellate algae,
I am the Host Organism,
You are the unicellular dinoflagellate algae,

Sweet Little unicellular dinoflagellate algae of mine,
Letting me use your chloroplasts to photosynthesize,
Providing me with carbon in exchange for the nutrients you obtain from my anabolic pathways,
Sweet Little unicellular dinoflagellate algae of mine,
