Leaves acclimate to sun and shade environments, Sun and shade leaves have contrasting biochemical and morphological characteristics such as
a.) Shade leaves increase light capture by having more total chlorophyll per reaction center, a higher ratio of chlorophyll b to chlorophyll a, and usually thinner laminae than sun leaves
b.) Sun leaves decrease CO2 assimilation by having less rubisco and can dissipate excess light energy and Morphologically they have thinner leaves and a larger palisade layer than shade leaves
c.) Shade leaves decrease light capture by having low total chlorophyll per reaction center, a higher ratio of chlorophyll b to chlorophyll a, and usually thicker laminae than sun leaves
d.) Sun leaves increase CO2 assimilation by having more rubisco and can dissipate excess light energy and Morphologically they have thicker leaves and a larger palisade layer than shade leaves
Which of the following combination from the above statements are TRUE?
