Modification of leaves

Leaves are often modified to perform functions other than photosynthesis.

Succulent leaves are also thickened leaves, but they are found above ground, still conduct photosynthesis, and function primarily in water storage

Spines are sharp projections derived from leaves that function in plant defense. Almost all cacti (in the plant family Cactaceae)  barberry and some Acacia species have spines 

Spines can also be formed from stipules (stipular spines) or bud scales.

Tendrils are another structure that can originate from multiple structures, including stems, leaves, or leaflets. 

leaves of glory lily are modified as tendrils
