Chapter 21, Problem 13SQ
Summary Introduction
Concept Introduction: Dinoflagellates living in the tropical areas have the ability to produce light. The light will protect the protists by startling the predator which tries to eat it. The flash produced from the light may function like a car alarm by attracting the attention of predators that would be a dinoflagellate eater.
