Question
Chapter 38.1, Problem 1C
Summary Introduction
To determine: The way in which the yellow color of phototropins relate to the wavelengths of light to which they respond.
Introduction: A phenomenon by which plants response to their environmental stimuli such as light, gravity, or water is known as tropism. There are different types of tropism that are named according to the stimulus associated with it.

Which of the following statements is true? Plants appear green because chlorophylls reflect and transmit yellow and green wavelengths of light, and absorb red and violet-blue wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb yellow and green wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb white wavelength of light.

- What is resonance and how is it involved in the fluorescence of chlorophylls and carotenes?arrow_forwardWhich color(s) of light does chlorophyll a reflect?arrow_forwardPhycobiliproteins are complex proteins in cyanobacteria that absorb light energy. There are three kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin-responsible for capturing green light, phycocyanin-responsible for capturing orange-red light, and allophycocyanin-responsible for capturing red light. Since light can only penetrate to certain depths in oceans, phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll.
