سؤال 24

Which statements about why a leaf looks green are true? Select all that apply.

  1. Green light is mostly reflected from the leafپاسخ درست
  2. Green light is the colour chlorophyll absorbs best
  3. Red and blue light are absorbed and used for photosynthesisپاسخ درست
  4. Every colour of light is absorbed equally by chlorophyll

توضیح

We see the colours a surface sends back to our eyes, so a leaf looking green tells us that green is the part of the light chlorophyll does least with. The colours that pigment takes in strongly are the ones that power photosynthesis, and a leaf that absorbed every colour equally would look black rather than green.
