Leaves are the vegetative organs of higher plants, and their lateral causes develop from the leaf primordium of plant stems. Leaves contain chloroplasts, which are the main organs of photosynthesis in plants. At the same time, the transpiration of plants is also realized through the stomata of leaves. Leaves can have various shapes, sizes, colors and textures.

Leaves only appear on real stems, that is, only vascular plants have leaves. All higher plants such as ferns, gymnosperms and angiosperms have leaves. In contrast, mosses, algae, fungi and lichens have no leaves. Only leaf-like structures can be found in these bacteria, but they can only be used as Analoga.

Leaves can have various shapes, sizes, colors and textures. Leaves can be clustered or scattered everywhere. The edges of leaves can be smooth or serrated. A complete leaf includes the following three parts: most leaves are wide and flat, suitable for receiving sunlight. The petiole supports the leaves and connects them with the stems. Stipules protect young leaves.
