Angiosperm Morphology: Heavily Cutinized Epidermis of Yucca Leaf
cross section: Yucca leaf
magnification: 400x
Berkshire Community College Bioscience Image Library
The leaves of Yucca show numerous structural adaptations that extend their tolerance to drought and desiccation. The epidermis is unseriate and heavily cutinized with sunken stomata evenly distributed on both adaxial and abaxial surfaces. Stomata overlay substomatal chambers and that are roofed by epidermal cells with ledge like extensions of cutin.
While the mesophyll is poorly differentiated at leaf tips the body of leaf shows one or two layers of tightly packed palisade mesophyll just beneath the epidermis.
