- The anatomy of a leaf includes the following structures1234:
- Cuticle layer: The outermost protective layer.
- Upper epidermis: The upper surface of the leaf.
- Palisade layer: Contains chloroplasts for photosynthesis.
- Spongy layer: Contains air spaces for gas exchange.
- Lower epidermis: The lower surface of the leaf.
- Stomata: Tiny pores on the lower epidermis for gas exchange.
- Leaf blade (lamina): The widest part of the leaf.
- Petiole: The stalk that attaches the leaf to the stem.
- Stipules: Small green appendages at the base of the petiole.

To view the original source information, use the "Learn more" links.The different layers of a leaf include the cuticle layer, the upper epidermis, the palisade layer, the spongy layer, the lower epidermis, and the stomata. These structures work together to enable plants to perform their cellular processes, photosynthesis, respiration, and excretion.www.sciencefacts.net/leaf-anatomy.htmlIn leaf anatomy, leaf tissues are composed of layers of plant cells. Different plant cell types form three main tissues found in leaves. These tissues include a mesophyll tissue layer that is sandwiched between two layers of epidermis. Leaf vascular tissue is located within the mesophyll layer.www.thoughtco.com/plant-leaves-and-leaf-anatom…Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Small green appendages usually found at the base of the petiole are known as stipules.openstax.org/books/biology-2e/pages/30-4-leavesIn cross-section, there are three major regions to see in the inside of a leaf: epidermis, mesophyll, and veins—or vascular bundles. The epidermal layer is one cell thick and covers the entire surface of the leaf. On the lower surface of the leaf blade, the epidermis is interrupted by stomata.
