The dermis and skeletal structure.
A leaf has a flat, thin structure with an outer epidermis layer that protects the leaf. Inside the leaf, there are layers of cells known as mesophyll, which contain chloroplasts for photosynthesis. The veins of the leaf transport water and nutrients throughout the leaf.
The waxy cuticle on the surface of a leaf helps prevent water loss by acting as a barrier. Additionally, stomata, microscopic pores on the leaf surface, open and close to regulate the exchange of gases and reduce water loss through transpiration.
Indusium is a protective layer found in some ferns that covers and shields the developing spores on the underside of the fronds. It helps to prevent the spores from drying out and protects them from external elements, aiding in their dispersal.
The body system that protects underlying organs from drying out is the integumentary system. This system also protects underlying organs from mechanical damage.
Skin mainly. It's the most waterproof structure many organisms have. Of course, many animals also need to protect their skin from drying out by keeping wet, like frogs and slugs. ^^

The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.

The organ system that protects underlying organs from drying out and mechanical damage is the integumentary system. This system is made up of the skin, hair and nails.
