     The picture below is of two oak leaves taken from the same tree. Leaf B is on average a much thicker than leaf A. It is likely that _____ is taken from the canopy (top of tree) and has ______ than ______ which is likely taken from a branch closer to the forest floor in more shaded environment.  more photosynthetic cells (palisade and spongy mesophyll) and has greater numbers of chloroplasts per surface area; Leaf B  more photosynthetic cells (palisade and spongy mesophyll) and has greater numbers of chloroplasts per surface area; Leaf A  less photosynthetic cells (palisade and spongy mesophyll) and has less numbers of chloroplasts per surface area, Leaf B  less photosynthetic cells (palisade and spongy mesophyll) and has less numbers of chloroplasts per surface area; Leaf A 
  
  Solution
Answer;LeafA:more photosynthetic cells(paliside and spongy mesophyll)and has greater numbers of chloroplasts per surface area;Leaf B
EXPLANATION;Generally the leaf A surface area is more than leaf B,so it is more exposed to sun ,so it has more scope of having paliside mesophyll which helps in photosynthesis
