The next day in biology class, when the teacher asked why algae were important, Artyom didn't even have to look at his notes. He just smiled, thinking of the tiny, glowing passenger who had shown him the world in a drop of water.
Artyom froze. Sitting right on the line where he was supposed to write "Cell Wall" was a microscopic creature, glowing with a bright emerald light.

"We are the lungs of the planet," the Chlamydomonas said, its red light-sensitive eye-spot glowing. "While you humans are busy walking around, we are here absorbing the sun and giving you the oxygen you breathe. Look at my chromatophore!" Sitting right on the line where he was

Artyom realized that this wasn't just a boring homework assignment. It was a silent, microscopic factory that kept the whole world alive. "Artyom! Dinner!" his mother called from the kitchen.
