Iridophores
from class: General Biology I Definition Iridophores are specialized pigment cells found in some invertebrates that reflect light, producing iridescent colors. They contain crystalline structures that can manipulate light wavelengths to create vibrant visual effects.
congrats on reading the definition of iridophores . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Iridophores are commonly found in molluscs and annelids within the superphylum Lophotrochozoa. These cells contain platelets made of guanine or other purines that help in reflecting light. Iridophores play a crucial role in camouflage, communication, and predator deterrence by creating shifting colors. Unlike chromatophores that absorb light to produce color, iridophores reflect specific wavelengths of light. The structural arrangement within iridophores can be altered to change the intensity and color of the reflected light. Review Questions What is the primary function of iridophores in certain invertebrates? How do iridophores differ from chromatophores in terms of their mechanism for producing color? Which compounds within iridophores are primarily responsible for reflecting light?
