Day 1

I've arrived from the sun as sunlight and energy and found myself in a strange green world! The place is called a chloroplast, and it's located in a plant leaf cell. Through the inner membrane, a light-absorbing molecule called a pigment, specifically chlorophyll, absorbs me, and I'm now in a thykaloid, a flat saclike membrane, which is in a stack of other thykaloids (the stack is called a grana). This is a natural occurrence (a photochemical reaction), but I hope my presence isn't TOO exciting...
