Leaves
"Leaves" are an important part of trees and one of the organs for photosynthesis in plants. Leaves are usually located at the end of branches and have a flat shape. They are used to maximize the absorption of sunlight and photosynthesis, converting carbon dioxide into oxygen and energy. Leaves are usually composed of blades, petioles and veins.
Leaves are the main part of leaves and usually have a variety of shapes and sizes, such as heart-shaped, oval, elliptical, etc. The leaves of different plants have different shapes. The surface of the leaves is usually smooth, but there may also be hair or other structures. The petiole connects the leaves to the branches and plays a role in supporting and transporting water and nutrients. Veins are the vascular system inside the leaves, which is responsible for transporting water and nutrients to the entire leaf.
