Visible Light Interaction with Pigments in the Palisade Cells ! Palisade cells contain chlorophyll pigments responsible for the absorption of the Blue and Red lights. ! Chlorophyll pigments produce a relatively lower absorption or higher reflection of the green light. ! This causes healthy foliage with a high chlorophyll content to appear green to our eyes.
