Veins don't.
They photosynthesise through the use of chloropyll (the stuff that makes the plant green) in the cells on the leaf.
Xylem and phloem are the two components that make up the veins of a plant. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem transports sugars and other organic compounds produced through photosynthesis to various parts of the plant.
Plants with numerous veins enhance photosynthesis by improving the transport of water, nutrients, and sugars throughout the plant. The extensive vascular network ensures efficient delivery of water from the roots to the leaves, where photosynthesis occurs, while also facilitating the distribution of the sugars produced during the process. Additionally, the increased surface area provided by multiple veins allows for greater light capture and gas exchange, optimizing the overall efficiency of photosynthesis.
To clarify: We boiled alcohol with a leaf and tested for starch with iodine (present in the veins), We also covered a leaf with tin foil and came back the next day. The leaf was more green in the veins and more discolored farther away from the veins. This lab was suppose to show us glucose is made by the leaf, but all it proves is that starch is in the veins, right?
The smaller veins in the leaf connect to the larger veins, which lead to the midrib, or central vein. This network of veins helps transport water, nutrients, and sugars to and from the leaf's cells for photosynthesis and other metabolic processes.
Photosynthesis.
Veins in a leaf carry water, nutrients, and sugars throughout the plant. Water and minerals are absorbed by the roots from the soil and transported through the veins to the rest of the plant for photosynthesis and growth. Sugars produced during photosynthesis are also transported through the veins to provide energy for various plant functions.

The most important function of a leaf is photosynthesis: the production of energy from sunlight, carbon dioxide and water. The shape of the leaf helps to maximize the sunlight receiving area and the veins in the leaf make it easier to move the raw materials and products of photosynthesis in and out of the leaf.
The purpose of the veins of a leaf is to hold nutrient and carry out the role of photosynthesis.

Used for photosynthesis in leaves, reproducction in flowers, transport of water through the veins
The smaller veins in the leaf connect to the larger veins, which lead to the midrib, or central vein. This network of veins helps transport water, nutrients, and sugars to and from the leaf's cells for photosynthesis and other metabolic processes.
The spaces between leaf veins are called interveinal areas. These areas are usually filled with chloroplasts, which are responsible for photosynthesis. The arrangement of veins and interveinal areas in leaves is important for nutrient and water transport.
The placement of the veins in a leaf can limit the effects of photosynthesis and transport water through the leaf and plant body. The location of the veins and the shape of the leaf are two of the factors used to determine the species of the plant.
The main parts of a leaf involved in photosynthesis are the chloroplasts, where photosynthesis occurs, and the stomata, which regulate gas exchange for photosynthesis. The mesophyll cells contain the majority of the chloroplasts where photosynthesis takes place, while the veins in the leaf provide the transport system for water and nutrients needed for photosynthesis.
Santol (Sandoricum koetjape) has prominent veins on its leaves, which are typically pinnate. The primary veins run from the base to the tip of the leaf, with secondary veins branching off. The leaf structure contributes to the plant's overall health and photosynthesis efficiency. Additionally, the fruit itself may display a subtle vein pattern on its surface.
