Leaves are the main organs for photosynthesis and respiration in plants, usually composed of leaves, petioles, and leaflets. They come in various shapes, including oval, heart-shaped, palm shaped, needle shaped, etc., with leaf veins distributed on the surface to transport nutrients. Chlorophyll makes leaves appear green, and after certain pigments decompose in autumn, they will reveal colorful hues such as red and yellow.

Leaves not only produce nutrients for plants, but also regulate water and temperature, and are the foundation of forest ecology - providing food and habitat for animals, and nourishing the soil after the decomposition of fallen leaves. From the sprouting of new shoots to the beautiful falling, the life cycle of a leaf silently records the flow of seasons and the wisdom of nature.
