How is a dicotyledonous leaf adapted for maximum sunlight and carbon dioxide for photosynthesis? 20 Points if ya help meh out lol

They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.

i think the answer is a.keratin is the pigment responsible for skin color.
