Palm leaf?
Water in a leaf is used for photosynthesis, which is the process by which plants make their own food. Water is essential for transporting nutrients and minerals from the soil to the leaves, and it also helps to maintain the turgidity of plant cells, allowing the leaf to remain rigid and upright for efficient light absorption.
A leaf makes glucose, a simple sugar, through the process of photosynthesis. This glucose is used by the plant for energy and as a building block for more complex molecules.
The cuticle in a leaf is the waxy covering on top and bottom of the leaf. It is used to conserve water.
A leaf tip is the pointed end of a leaf, which can vary in shape and size depending on the plant species. It is typically the part of the leaf that is farthest from the stem. Leaf tips can be used to identify different types of plants.

Fans (both electric ones and hand held ones) are used to create wind, mainly to speed evaporation. The speeding of evaporation is mainly done to make human bodies cooler, but it is also used in drying things recently washed with water (e.g., floors or automobiles). Fans are also used in some traditional cooking to oxygenate charcoal and make it burn hotter. Folding fans are also used as props by some traditional storytellers.

Not all fans are electrical devices, but many are. To be effective, a fan must have some source of energy input to cause them to move air. Many ancient cultures used hand-powered or hand-held fans. Older automobiles used mechanically powered fans, although most new cars now incorporate electric fans. Typical household fans, however, are powered by electrical motors.
Hand fans are commonly referred to as "folding fans" or simply "fans." They come in various styles, materials, and designs, often used for both practical purposes, such as cooling, and as decorative accessories. In specific cultural contexts, they may have unique names, like "uchiwa" in Japan or "abanico" in Spanish-speaking countries.
