To make photosynthesis occur, you need 3 raw materials : carbon dioxide, water, and sunlight. Carbon dioxide comes from air, water from xylem roots, and sunlight from sunlight! Below is a good picture which explains about photosynthesis.

As you can see here in the picture, sunlight, carbon dioxide, and water enter the leaf through either sunlight, xylem roots, or air. I plant then uses this, and the end products are glucose (sugar) and oxygen. The oxygen is what we breathe in. When we eat a plant, we eat that glucose that is getting released. Breaking down stored carbohydrates or sugar from oxygen is called cellular respiration, which is the opposite of photosynthesis. HOPE THIS HELPS, DUDE!
