Leaf Structure Model

This leaf structure model is mounted on a stand and numbered, with an English key card, as a visual aid for studying leaf anatomy. It shows the internal structure of a leaf, and the numbering and key card are there to identify each part. The details are hand-painted with eco-friendly paint.

Models like this are used in educational settings to teach students about the structure and function of leaves, which are essential for photosynthesis and plant survival.

Parts of a leaf

• Cuticle: a protective layer on the outer surface of the leaf
• Epidermis: the outer layer of cells, often with a waxy cuticle on top to prevent water loss
• Mesophyll: the tissue in the middle of the leaf, divided into palisade mesophyll (columnar cells, often packed with chloroplasts for photosynthesis) and spongy mesophyll (loosely arranged cells with air spaces)
• Vascular bundles: these contain xylem (which transports water and minerals) and phloem (which transports sugars)
• Bundle sheath: cells surrounding the vascular bundles
• Stomata: pores, usually on the underside of the leaf, that allow for gas exchange (carbon dioxide in, oxygen and water vapor out)
