Tree, artwork. Trees are perennial woody plants that can grow to large sizes and be long-lived. They obtain carbon dioxide and oxygen from the air through their leaves (the site of photosynthesis), and water and nutrients from the soil through their roots. Their roots can help reduce soil erosion, and their foliage can be both habitat and food.
