Mammalian eyes sense light because the photoreceptor cells have molecules called opsins that change structure when exposed to light. Which of the following plant molecules is most analogous to mammalian opsins in their light-sensing ability?

Question

Quizplus · Accepted Answer

Phytochromes are the plant molecules most analogous to mammalian opsins in terms of their light-sensing ability. Like opsins, phytochromes change their structure in response to light, allowing plants to detect light and respond to it, such as by initiating germination or flowering.
