I don't know how this question should be answer!!!

Parts of a leaf (Morphology)

1. Apex - tip of the leaf

2. Blade or Lamina - the flat part of the leaf (the leaf p***e in layman's term)

3. Petiole - the stalk that holds the leaf

4. Base - base of the leaf

5. Leaf Sheath

6. Leaf Margin

Anatomy

1. Cuticle layer - outer layer of the leaf that reflects extreme UV rays

2. Palisade Layer - leaf layer that contains the chlrorenchyma cells that aids in trapping lights

3. Epidermal Layer - next layer to cuticle layer that provides support and strong hold on inner layers.

4. Spongy Mesophyll Layer - leaf layer for gas and other nutrients exchange

5. Vascular Bundles - aids in transfer of nutrients and water
