B) palisade layer
The most photosynthesis in a leaf occurs in the palisade layer, which is located near the upper surface of the leaf. The palisade layer contains many chloroplasts, which are the organelles responsible for photosynthesis. The chloroplasts contain chlorophyll, which absorbs light energy to convert carbon dioxide and water into glucose and oxygen. The palisade layer is located near the upper surface of the leaf because it receives the most direct sunlight and therefore has the highest concentration of light energy needed for photosynthesis to occur.
The cuticle, on the other hand, is a waxy layer that covers the outer surface of the leaf to prevent water loss; it does not have chloroplasts and therefore cannot perform photosynthesis. The spongy layer is a loose tissue located beneath the palisade layer; it contains fewer chloroplasts and is involved more in gas exchange than in photosynthesis. The veins of the leaf contain the transport system for water, nutrients, and sugars produced during photosynthesis. They are not directly involved in the process of photosynthesis, but are essential for the movement of substances to and from the site of photosynthesis in the palisade layer.
