Which statement correctly describes the relationship between leaf anatomy and photosynthesis?

1. Palisade mesophyll stores starch, spongy mesophyll absorbs light, and veins produce chlorophyll for photosynthesis
2. The cuticle carries out gas exchange, xylem absorbs light energy, and phloem produces oxygen for the plant
3. Stomata synthesize sugars directly, the epidermis conducts water upward, and veins release carbon dioxide into the air
4. Palisade mesophyll absorbs light, spongy mesophyll supports gas diffusion, and veins supply water and export sugars
