2. Leaves – The Big Ideas Leaf cells have chlorophyll. Photosynthesis takes place in leaf cells. During photosynthesis, light energy, trapped by chlorophyll, is used to transform carbon dioxide and water into carbohydrates and oxygen. Veins in leaves allow water and nutrients to travel around the plant.
