Question

How does frame (b) Action Spectrum best support the image seen here of how a chloroplast collects and emits light energy as photosynthesis progresses? This additional image may support your thinking. (1 point) Responses Frame b shows that in a chloroplast the collection of pigments don't absorb as much green light as they do other colors (wavelengths). Frame b shows that in a chloroplast the collection of pigments don't absorb as much green light as they do other colors (wavelengths). Frame b shows that greenlight is absorbed more than other colors of light by pigments in chloroplasts. Frame b shows that greenlight is absorbed more than other colors of light by pigments in chloroplasts. Frame b shows that only green light is used in photosynthesis to produce oxygen. Frame b shows that only green light is used in photosynthesis to produce oxygen. Frame b shows that red and blue light are not absorbed as much as yellow light.

Answer 1

The correct response is:

Frame b shows that in a chloroplast the collection of pigments don't absorb as much green light as they do other colors (wavelengths).

This statement best supports the image of how a chloroplast collects and emits light energy during photosynthesis because it indicates that while chloroplasts utilize various wavelengths of light for photosynthesis, they are less effective at absorbing green light compared to red and blue light. This explains why plants often appear green, as the chlorophyll pigments absorb light mainly in the red and blue spectra and reflect green light instead. This insight aligns with the action spectrum, illustrating how different wavelengths contribute to the photosynthetic process.
